+To build:
+
+ % ./configure
+
+ Edit config.h to change the configuration options if necessary.
+
+ % make
+
+
+To install:
+
+ % make install
+
+ Edit one of your system rc files to run thttpd at boot time. Do NOT
+ run it from inetd, that setup is inefficient so thttpd doesn't support it.
+
+
+Red Hat:
+
+ On Red Hat Linux systems you can use RPM to install thttpd, like so:
+
+ cd /usr/src/redhat/SOURCES
+ wget http://www.acme.com/software/thttpd/thttpd-2.29.tar.gz
+ rpm -ta thttpd-2.29.tar.gz
+ rpm -i /usr/src/redhat/RPMS/i386/thttpd-2.29-1.i386.rpm
+
+
+Solaris:
+
+ If you're running Solaris and you want to use the security-enhancing
+ chroot feature, then you must create the TCP device files in the chroot
+ tree. There is no way around this, Solaris needs these files to accept
+ network connections. You need /dev/tcp, which is a symbolic link like so:
+ /dev/tcp -> ../devices/pseudo/clone@0:tcp
+ And you also need the file it points to:
+ crw-rw-rw- bin 11, 42 May 24 21:32 /devices/pseudo/clone@0:tcp
+ You probably need some other files too, such as shared libraries and
+ a tmp directory. Check out the man page for ftpd, it has a big long
+ shell script for setting up an anonymous ftp area that should also
+ work for thttpd.

+ thttpd - tiny/turbo/throttling HTTP server
+ version 2.29 of 23May2018
+
+thttpd is a simple, small, portable, fast, and secure HTTP server.
+
+Simple: It handles only the minimum necessary to implement HTTP/1.1.
+
+Small: See the size comparison chart at
+http://www.acme.com/software/thttpd/notes.html#sizes. It also has a
+very small run-time size, since it does not fork and is very careful about
+memory allocation.
+
+Portable: It compiles cleanly on FreeBSD 2.x/3.x, SunOS 4.1.x, Solaris 2.x,
+BSD/OS 2.x, Linux 1.2.x, OSF/1 (on a 64-bit Alpha), and no doubt many others.
+
+Fast: In typical use it's about as fast as the best full-featured servers
+(Apache, NCSA, Netscape). Under extreme load it's much faster.
+
+Secure: It goes to great lengths to protect the web server machine
+against attacks and breakins from other sites.
+
+It also has one extremely useful feature (URL-traffic-based throttling) that
+no other server currently has.
+
+See the manual entry for more details. See the INSTALL file for
+configuration and installation instructions. Check the web page
+(http://www.acme.com/software/thttpd/) for updates, or add yourself to
+the mailing list by sending a "subscribe" to thttpd-announce-request@mail.acme.com.

+dnl This test is for network applications that need socket() and
+dnl gethostbyname() -ish functions. Under Solaris, those applications
+dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
+dnl with "-lnsl" but should *not* link with "-lsocket" because
+dnl libsocket.a breaks a number of things (for instance:
+dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
+dnl versions of IRIX).
+dnl
+dnl Unfortunately, many application developers are not aware of this,
+dnl and mistakenly write tests that cause -lsocket to be used under
+dnl IRIX. It is also easy to write tests that cause -lnsl to be used
+dnl under operating systems where neither are necessary (or useful),
+dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
+dnl
+dnl This test exists so that every application developer does not test
+dnl this in a different, and subtly broken fashion.
+
+dnl It has been argued that this test should be broken up into two
+dnl seperate tests, one for the resolver libraries, and one for the
+dnl libraries necessary for using Sockets API. Unfortunately, the two
+dnl are carefully intertwined and allowing the autoconf user to use
+dnl them independantly potentially results in unfortunate ordering
+dnl dependancies -- as such, such component macros would have to
+dnl carefully use indirection and be aware if the other components were
+dnl executed. Since other autoconf macros do not go to this trouble,
+dnl and almost no applications use sockets without the resolver, this
+dnl complexity has not been implemented.
+dnl
+dnl The check for libresolv is in case you are attempting to link
+dnl statically and happen to have a libresolv.a lying around (and no
+dnl libnsl.a).

+.TH redirect 8 "23 September 1995"
+.SH NAME
+redirect - simple redirection CGI program
+.SH SYNOPSIS
+.B redirect
+.SH DESCRIPTION
+.PP
+Three steps to set up a redirection:
+.PP
+1. Make sure your web server is set up to allow CGI programs.
+.PP
+2. Make a symbolic link from the file or directory you want to redirect,
+pointing at this program in the CGI bin directory.
+.PP
+3. Add an entry to the file ".redirects" in the directory where your
+http server runs CGI programs. For most servers, this is the
+directory where the given CGI program lives. The format of the
+file is a bunch of lines with a filename, whitespace, and the new
+URL. For example:
+.nf
+ /test/oldfile.html http://www.acme.com/test/newfile.html
+.fi
+The easiest way to figure out precisely what filename to put into .redirects
+is to set up the symlink and then click on it.
+You'll get back a "404 Not Found" page which includes the filename
+as received by the redirect program, and that's what you want to use.
+.PP
+You can also add a wildcard specification to redirect whole groups of files.
+For example:
+.nf
+ /wildtest/* http://www.acme.com/test-
+.fi
+will cause an access to the /wildtest/somefile.html to be redirected to
+http://www.acme.com/test-somefile.html. (Note that the asterisk need not
+be preceded by a slash.)
+.PP
+Note: this is designed for thttpd (http://www.acme.com/software/thttpd/)
+and using it with other web servers may require some hacking. A possible
+gotcha is with the symbolic link from the old file pointing at this
+script - servers other than thttpd may not allow that link to be run
+as a CGI program, because they don't check the link to see that it
+points into the allowed CGI directory.
+.SH "SEE ALSO"
+thttpd(8)
+.SH "BUGS / DEFICIENCIES"
+.PP
+It would be really cool to have this program look for
+the .redirects file in the same directory as the file being redirected,
+instead of in the binaries directory. Unfortunately, this appears
+to be impossible with the information CGI gives, plus the non-standardized
+but widespread practice of running CGI programs in the directory where
+the binary lives. Perhaps CGI 1.2 will address this.
+.PP
+The wildcard mechanism is very primitive.
+In particular, any characters that follow the asterisk are blithely
+ignored.

+.SH NAME
+ssi - server-side-includes CGI program
+.SH SYNOPSIS
+.B ssi
+.SH DESCRIPTION
+.PP
+This is an external CGI program that gives you the same functionality
+as the built-in server-side-includes feature in some HTTP daemons.
+It is written for use with thttpd(8), but should be easy to adapt
+to other systems.
+.PP
+To use this program, first make sure it is installed in your server's
+CGI area, and that CGI is enabled.
+Then set up your URLs with the path to the document you want parsed
+as the "pathinfo".
+That's the part of the URL that comes after the CGI program name.
+For example, if the URL to this program is:
+.nf
+ http://www.acme.com/cgi-bin/ssi
+.fi
+and the url for your document is:
+.nf
+ http://www.acme.com/users/wecoyote/doc.html
+.fi
+then the compound URL that gives you the document filtered through the
+program would be:
+.nf
+ http://www.acme.com/cgi-bin/ssi/users/wecoyote/doc.html
+.fi
+.PP
+The format description below is adapted from
+http://hoohoo.ncsa.uiuc.edu/docs/tutorials/includes.html
+.SH "INCLUDE FORMAT"
+.PP
+All directives are formatted as SGML comments within the document.
+This is in case the document should ever find itself in the client's
+hands unparsed.
+Each directive has the following format:
+.nf
+ <!--#command tag1="value1" tag2="value2" -->
+.fi
+Each command takes different arguments, most only accept one tag at a time.
+Here is a breakdown of the commands and their associated tags:
+.IP * 4
+.BR config :
+The config directive controls various aspects of the file parsing.
+There are two valid tags:
+.IP o 8
+.BR timefmt :
+gives the server a new format to use when providing dates.
+This is a string compatible with the strftime library call.
+.IP o 8
+.BR sizefmt :
+determines the formatting to be used when displaying the
+size of a file.
+Valid choices are bytes, for a formatted byte count
+(formatted as 1,234,567), or abbrev for an abbreviated version
+displaying the number of kilobytes or megabytes the file occupies.
+.IP * 4
+.BR include :
+Inserts the text of another document into the parsed document.
+The inserted file is parsed recursively, so it can contain
+server-side-include directives too.
+This command accepts two tags:
+.IP o 8
+.BR virtual :
+Gives a virtual path to a document on the server.
+.IP o 8
+.BR file :
+Gives a pathname relative to the current directory. ../ cannot
+be used in this pathname, nor can absolute paths be used.
+.IP * 4
+.BR echo :
+Prints the value of one of the include variables (defined below).
+Any dates are printed subject to the currently configured timefmt.
+The only valid tag to this command is var, whose value is the name of the
+variable you wish to echo.
+.IP * 4
+.BR fsize :
+prints the size of the specified file,
+subject to the sizefmt parameter to the config command.
+Valid tags are the same as with the include command.
+.IP * 4
+.BR flastmod :
+prints the last modification date of the specified file, subject
+to the formatting preference given by the timefmt parameter to config.
+Valid tags are the same as with the include command.
+.SH VARIABLES
+.PP
+A number of variables are made available to parsed documents.
+In addition to
+the CGI variable set, the following variables are made available:
+.IP * 4
+.BR DOCUMENT_NAME :
+The current filename.
+.IP * 4
+.BR DOCUMENT_URI :
+The virtual path to this document (such as /~robm/foo.shtml).
+.IP * 4
+.BR QUERY_STRING_UNESCAPED :
+The unescaped version of any search query the client sent.
+.IP * 4
+.BR DATE_LOCAL :
+The current date, local time zone.
+Subject to the timefmt parameter to the config command.
+.IP * 4
+.BR DATE_GMT :
+Same as DATE_LOCAL but in Greenwich mean time.
+.IP * 4
+.BR LAST_MODIFIED :
+The last modification date of the current document.
+Subject to timefmt like the others.
+.SH "BUGS / DEFICIENCIES"
+.PP
+Does not implement the "exec" directive.
+Actually, I consider this neither a bug nor a deficiency, but some may.
+.SH "SEE ALSO"

+ mmap shared fixed at somewhere currently unmapped
+ mmap shared fixed at somewhere already mapped

+ VM page cache was not coherent with the filesystem buffer cache
+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propogated back to all the places they're supposed to be.
+
+ Grep wants private fixed already mapped.
+ The main things grep needs to know about mmap are:
+ * does it exist and is it safe to write into the mmap'd area
+ * how to use it (BSD variants) */

+%description
+Thttpd is a very compact no-frills httpd serving daemon that can handle
+very high loads. While lacking many of the advanced features of
+Apachee, thttpd operates without forking and is extremely efficient in
+memory use. Basic support for cgi scripts, authentication, and ssi is
+provided for. Advanced features include the ability to throttle traffic.

+Depends: ${shlibs:Depends}, ${misc:Depends}
+Description: tiny/turbo/throttling HTTP server
+ thttpd is a simple, small, portable, fast, and secure HTTP server.
+ .
+ Simple:
+ It handles only the minimum necessary to implement HTTP/1.1. Well, maybe a little more than the minimum.
+ Small:
+ See the comparison chart. It also has a very small run-time size, since it does not fork and is very careful about memory allocation.
+ Portable:
+ It compiles cleanly on most any Unix-like OS, specifically including FreeBSD, SunOS 4, Solaris 2, BSD/OS, Linux, OSF.
+ Fast:
+ In typical use it's about as fast as the best full-featured servers (Apache, NCSA, Netscape). Under extreme load it's much faster.
+ Secure:
+ It goes to great lengths to protect the web server machine against attacks and breakins from other sites.
+ .
+ It also has one extremely useful feature (URL-traffic-based throttling) that no other server currently has. Plus, it supports IPv6 out of the box, no patching required

+The xsltproc binary is found in the xsltproc package. The XSL files are in

+Alternatively use the xmlto command/package. That will also automatically

+
+Notes for using docbook2x: docbook2x-man does not automatically create the
+AUTHOR(S) and COPYRIGHT sections. In this case, please add them manually as

+Description: tiny/turbo/throttling HTTP server
+ thttpd is a simple, small, portable, fast, and secure HTTP server.
+ .
+ Simple:
+ It handles only the minimum necessary to implement HTTP/1.1. Well, maybe a little more than the minimum.
+ Small:
+ See the comparison chart. It also has a very small run-time size, since it does not fork and is very careful about memory allocation.
+ Portable:
+ It compiles cleanly on most any Unix-like OS, specifically including FreeBSD, SunOS 4, Solaris 2, BSD/OS, Linux, OSF.
+ Fast:
+ In typical use it's about as fast as the best full-featured servers (Apache, NCSA, Netscape). Under extreme load it's much faster.
+ Secure:
+ It goes to great lengths to protect the web server machine against attacks and breakins from other sites.
+ .
+ It also has one extremely useful feature (URL-traffic-based throttling) that no other server currently has. Plus, it supports IPv6 out of the box, no patching required

+.SH DESCRIPTION
+.PP
+.I thttpd
+is a simple, small, fast, and secure HTTP server.
+It doesn't have a lot of special features, but it suffices for most uses of
+the web, it's about as fast as the best full-featured servers (Apache, NCSA,
+Netscape),
+and it has one extremely useful feature (URL-traffic-based throttling)
+that no other server currently has.
+.SH OPTIONS
+.TP
+.B -C
+Specifies a config-file to read.
+All options can be set either by command-line flags or in the config file.
+See below for details.
+.TP
+.B -p
+Specifies an alternate port number to listen on.
+The default is 80.
+The config-file option name for this flag is "port",
+and the config.h option is DEFAULT_PORT.
+.TP
+.B -d
+Specifies a directory to chdir() to at startup.
+This is merely a convenience - you could just as easily
+do a cd in the shell script that invokes the program.
+The config-file option name for this flag is "dir",
+and the config.h options are WEBDIR, USE_USER_DIR.
+.TP
+.B -r
+Do a chroot() at initialization time, restricting file access
+to the program's current directory.
+If -r is the compiled-in default, then -nor disables it.
+See below for details.
+The config-file option names for this flag are "chroot" and "nochroot",
+and the config.h option is ALWAYS_CHROOT.
+.TP
+.B -dd
+Specifies a directory to chdir() to after chrooting.
+If you're not chrooting, you might as well do a single chdir() with
+the -d flag.
+If you are chrooting, this lets you put the web files in a subdirectory
+of the chroot tree, instead of in the top level mixed in with the
+chroot files.
+The config-file option name for this flag is "data_dir".
+.TP
+.B -nos
+Don't do explicit symbolic link checking.
+Normally, thttpd explicitly expands any symbolic links in filenames,
+to check that the resulting path stays within the original document tree.
+If you want to turn off this check and save some CPU time, you can use
+the -nos flag, however this is not recommended.
+Note, though, that if you are using the chroot option, the symlink
+checking is unnecessary and is turned off, so the safe way to save
+those CPU cycles is to use chroot.
+The config-file option names for this flag are "symlinkcheck" and "nosymlinkcheck".
+.TP
+.B -v
+Do el-cheapo virtual hosting.
+If -v is the compiled-in default, then -nov disables it.
+See below for details.
+The config-file option names for this flag are "vhost" and "novhost",
+and the config.h option is ALWAYS_VHOST.
+.TP
+.B -g
+Use a global passwd file.
+This means that every file in the entire document tree is protected by
+the single .htpasswd file at the top of the tree.
+Otherwise the semantics of the .htpasswd file are the same.
+If this option is set but there is no .htpasswd file in
+the top-level directory, then thttpd proceeds as if the option was
+not set - first looking for a local .htpasswd file, and if that doesn't
+exist either then serving the file without any password.
+If -g is the compiled-in default, then -nog disables it.
+The config-file option names for this flag are "globalpasswd" and
+"noglobalpasswd",
+and the config.h option is ALWAYS_GLOBAL_PASSWD.
+.TP
+.B -u
+Specifies what user to switch to after initialization when started as root.
+The default is "nobody".
+The config-file option name for this flag is "user",
+and the config.h option is DEFAULT_USER.
+.TP
+.B -c
+Specifies a wildcard pattern for CGI programs, for instance "**.cgi"
+or "/cgi-bin/*".
+See below for details.
+The config-file option name for this flag is "cgipat",
+and the config.h option is CGI_PATTERN.
+.TP
+.B -t
+Specifies a file of throttle settings.
+See below for details.
+The config-file option name for this flag is "throttles".
+.TP
+.B -h
+Specifies a hostname to bind to, for multihoming.
+The default is to bind to all hostnames supported on the local machine.
+See below for details.
+The config-file option name for this flag is "host",
+and the config.h option is SERVER_NAME.
+.TP
+.B -l
+Specifies a file for logging.
+If no -l argument is specified, thttpd logs via syslog().
+If "-l /dev/null" is specified, thttpd doesn't log at all.
+The config-file option name for this flag is "logfile".
+.TP
+.B -i
+Specifies a file to write the process-id to.
+If no file is specified, no process-id is written.
+You can use this file to send signals to thttpd.
+See below for details.
+The config-file option name for this flag is "pidfile".
+.TP
+.B -T
+Specifies the character set to use with text MIME types.
+The default is UTF-8.
+The config-file option name for this flag is "charset",
+and the config.h option is DEFAULT_CHARSET.
+.TP
+.B -P
+Specifies a P3P server privacy header to be returned with all responses.
+See http://www.w3.org/P3P/ for details.
+Thttpd doesn't do anything at all with the string except put it in the
+P3P: response header.
+The config-file option name for this flag is "p3p".
+.TP
+.B -M
+Specifies the number of seconds to be used in a "Cache-Control: max-age"
+header to be returned with all responses.
+An equivalent "Expires" header is also generated.
+The default is no Cache-Control or Expires headers,
+which is just fine for most sites.
+The config-file option name for this flag is "max_age".
+.TP
+.B -V
+Shows the current version info.
+.TP
+.B -D
+This was originally just a debugging flag, however it's worth mentioning
+because one of the things it does is prevent thttpd from making itself
+a background daemon.
+Instead it runs in the foreground like a regular program.
+This is necessary when you want to run thttpd wrapped in a little shell
+script that restarts it if it exits.
+.SH "CONFIG-FILE"
+.PP
+All the command-line options can also be set in a config file.
+One advantage of using a config file is that the file can be changed,
+and thttpd will pick up the changes with a restart.
+.PP
+The syntax of the config file is simple, a series of "option" or
+"option=value" separated by whitespace.
+The option names are listed above with their corresponding command-line flags.
+.SH "CHROOT"
+.PP
+chroot() is a system call that restricts the program's view
+of the filesystem to the current directory and directories
+below it.
+It becomes impossible for remote users to access any file
+outside of the initial directory.
+The restriction is inherited by child processes, so CGI programs get it too.
+This is a very strong security measure, and is recommended.
+The only downside is that only root can call chroot(), so this means
+the program must be started as root.
+However, the last thing it does during initialization is to
+give up root access by becoming another user, so this is safe.
+.PP
+The program can also be compile-time configured to always
+do a chroot(), without needing the -r flag.
+.PP
+Note that with some other web servers, such as NCSA httpd, setting
+up a directory tree for use with chroot() is complicated, involving
+creating a bunch of special directories and copying in various files.
+With thttpd it's a lot easier, all you have to do is make sure
+any shells, utilities, and config files used by your CGI programs and
+scripts are available.
+If you have CGI disabled, or if you make a policy that all CGI programs
+must be written in a compiled language such as C and statically linked,
+then you probably don't have to do any setup at all.
+.PP
+However, one thing you should do is tell syslogd about the chroot tree,
+so that thttpd can still generate syslog messages.
+Check your system's syslodg man page for how to do this.
+In FreeBSD you would put something like this in /etc/rc.conf:
+.nf
+ syslogd_flags="-l /usr/local/www/data/dev/log"
+.fi
+Substitute in your own chroot tree's pathname, of course.
+Don't worry about creating the log socket, syslogd wants to do that itself.
+(You may need to create the dev directory.)
+In Linux the flag is -a instead of -l, and there may be other differences.
+.PP
+Relevant config.h option: ALWAYS_CHROOT.
+.SH "CGI"
+.PP
+thttpd supports the CGI 1.1 spec.
+.PP
+In order for a CGI program to be run, its name must match the pattern
+specified either at compile time or on the command line with the -c flag.
+This is a simple shell-style filename pattern.
+You can use * to match any string not including a slash,
+or ** to match any string including slashes,
+or ? to match any single character.
+You can also use multiple such patterns separated by |.
+The patterns get checked against the filename
+part of the incoming URL.
+Don't forget to quote any wildcard characters so that the shell doesn't
+mess with them.
+.PP
+Restricting CGI programs to a single directory lets the site administrator
+review them for security holes, and is strongly recommended.
+If there are individual users that you trust, you can enable their
+directories too.
+.PP
+If no CGI pattern is specified, neither here nor at compile time,
+then CGI programs cannot be run at all.
+If you want to disable CGI as a security measure, that's how you do it, just
+comment out the patterns in the config file and don't run with the -c flag.
+.PP
+Note: the current working directory when a CGI program gets run is
+the directory that the CGI program lives in.
+This isn't in the CGI 1.1 spec, but it's what most other HTTP servers do.
+.PP
+Relevant config.h options: CGI_PATTERN, CGI_TIMELIMIT, CGI_NICE, CGI_PATH, CGI_LD_LIBRARY_PATH, CGIBINDIR.
+.SH "BASIC AUTHENTICATION"
+.PP
+Basic Authentication is available as an option at compile time.
+If enabled, it uses a password file in the directory to be protected,
+called .htpasswd by default.
+This file is formatted as the familiar colon-separated
+username/encrypted-password pair, records delimited by newlines.
+The protection does not carry over to subdirectories.
+The utility program htpasswd(1) is included to help create and
+modify .htpasswd files.
+.PP
+Relevant config.h option: AUTH_FILE
+.SH "THROTTLING"
+.PP
+The throttle file lets you set maximum byte rates on URLs or URL groups.
+You can optionally set a minimum rate too.
+The format of the throttle file is very simple.
+A # starts a comment, and the rest of the line is ignored.
+Blank lines are ignored.
+The rest of the lines should consist of a pattern, whitespace, and a number.
+The pattern is a simple shell-style filename pattern, using ?/**/*, or
+multiple such patterns separated by |.
+.PP
+The numbers in the file are byte rates, specified in units of bytes per second.
+For comparison, a v.90 modem gives about 5000 B/s depending on compression,
+a double-B-channel ISDN line about 12800 B/s, and a T1 line is about
+150000 B/s.
+If you want to set a minimum rate as well, use number-number.
+.PP
+Example:
+.nf
+ # throttle file for www.acme.com
+
+ ** 2000-100000 # limit total web usage to 2/3 of our T1,
+ # but never go below 2000 B/s
+ **.jpg|**.gif 50000 # limit images to 1/3 of our T1
+ **.mpg 20000 # and movies to even less
+ jef/** 20000 # jef's pages are too popular
+.fi
+.PP
+Throttling is implemented by checking each incoming URL filename against all
+of the patterns in the throttle file.
+The server accumulates statistics on how much bandwidth each pattern
+has accounted for recently (via a rolling average).
+If a URL matches a pattern that has been exceeding its specified limit,
+then the data returned is actually slowed down, with
+pauses between each block.
+If that's not possible (e.g. for CGI programs) or if the bandwidth has gotten
+way larger than the limit, then the server returns a special code
+saying 'try again later'.
+.PP
+The minimum rates are implemented similarly.
+If too many people are trying to fetch something at the same time,
+throttling may slow down each connection so much that it's not really
+useable.
+Furthermore, all those slow connections clog up the server, using
+up file handles and connection slots.
+Setting a minimum rate says that past a certain point you should not
+even bother - the server returns the 'try again later" code and the
+connection isn't even started.
+.PP
+There is no provision for setting a maximum connections/second throttle,
+because throttling a request uses as much cpu as handling it, so
+there would be no point.
+There is also no provision for throttling the number of simultaneous
+connections on a per-URL basis.
+However you can control the overall number of connections for the whole
+server very simply, by setting the operating system's per-process file
+descriptor limit before starting thttpd.
+Be sure to set the hard limit, not the soft limit.
+.SH "MULTIHOMING"
+.PP
+Multihoming means using one machine to serve multiple hostnames.
+For instance, if you're an internet provider and you want to let
+all of your customers have customized web addresses, you might
+have www.joe.acme.com, www.jane.acme.com, and your own www.acme.com,
+all running on the same physical hardware.
+This feature is also known as "virtual hosts".
+There are three steps to setting this up.
+.PP
+One, make DNS entries for all of the hostnames.
+The current way to do this, allowed by HTTP/1.1, is to use CNAME aliases,
+like so:
+.nf
+ www.acme.com IN A 192.100.66.1
+ www.joe.acme.com IN CNAME www.acme.com
+ www.jane.acme.com IN CNAME www.acme.com
+.fi
+However, this is incompatible with older HTTP/1.0 browsers.
+If you want to stay compatible, there's a different way - use A records
+instead, each with a different IP address, like so:
+.nf
+ www.acme.com IN A 192.100.66.1
+ www.joe.acme.com IN A 192.100.66.200
+ www.jane.acme.com IN A 192.100.66.201
+.fi
+This is bad because it uses extra IP addresses, a somewhat scarce resource.
+But if you want people with older browsers to be able to visit your
+sites, you still have to do it this way.
+.PP
+Step two.
+If you're using the modern CNAME method of multihoming, then you can
+skip this step.
+Otherwise, using the older multiple-IP-address method you
+must set up IP aliases or multiple interfaces for the extra addresses.
+You can use ifconfig(8)'s alias command to tell the machine to answer to
+all of the different IP addresses.
+Example:
+.nf
+ ifconfig le0 www.acme.com
+ ifconfig le0 www.joe.acme.com alias
+ ifconfig le0 www.jane.acme.com alias
+.fi
+If your OS's version of ifconfig doesn't have an alias command, you're
+probably out of luck (but see http://www.acme.com/software/thttpd/notes.html).
+.PP
+Third and last, you must set up thttpd to handle the multiple hosts.
+The easiest way is with the -v flag, or the ALWAYS_VHOST config.h option.
+This works with either CNAME multihosting or multiple-IP multihosting.
+What it does is send each incoming request to a subdirectory based on the
+hostname it's intended for.
+All you have to do in order to set things up is to create those subdirectories
+in the directory where thttpd will run.
+With the example above, you'd do like so:
+.nf
+ mkdir www.acme.com www.joe.acme.com www.jane.acme.com
+.fi
+If you're using old-style multiple-IP multihosting, you should also create
+symbolic links from the numeric addresses to the names, like so:
+.nf
+ ln -s www.acme.com 192.100.66.1
+ ln -s www.joe.acme.com 192.100.66.200
+ ln -s www.jane.acme.com 192.100.66.201
+.fi
+This lets the older HTTP/1.0 browsers find the right subdirectory.
+.PP
+There's an optional alternate step three if you're using multiple-IP
+multihosting: run a separate thttpd process for each hostname, using
+the -h flag to specify which one is which.
+This gives you more flexibility, since you can run each of these processes
+in separate directories, with different throttle files, etc.
+Example:
+.nf
+ thttpd -r -d /usr/www -h www.acme.com
+ thttpd -r -d /usr/www/joe -u joe -h www.joe.acme.com
+ thttpd -r -d /usr/www/jane -u jane -h www.jane.acme.com
+.fi
+But remember, this multiple-process method does not work with CNAME
+multihosting - for that, you must use a single thttpd process with
+the -v flag.
+.SH "CUSTOM ERRORS"
+.PP
+thttpd lets you define your own custom error pages for the various
+HTTP errors.
+There's a separate file for each error number, all stored in one
+special directory.
+The directory name is "errors", at the top of the web directory tree.
+The error files should be named "errNNN.html", where NNN is the error number.
+So for example, to make a custom error page for the authentication failure
+error, which is number 401, you would put your HTML into the file
+"errors/err401.html".
+If no custom error file is found for a given error number, then the
+usual built-in error page is generated.
+.PP
+If you're using the virtual hosts option, you can also have different
+custom error pages for each different virtual host.
+In this case you put another "errors" directory in the top of that
+virtual host's web tree.
+thttpd will look first in the virtual host errors directory, and
+then in the server-wide errors directory, and if neither of those
+has an appropriate error file then it will generate the built-in error.
+.SH "NON-LOCAL REFERRERS"
+.PP
+Sometimes another site on the net will embed your image files in their
+HTML files, which basically means they're stealing your bandwidth.
+You can prevent them from doing this by using non-local referrer filtering.
+With this option, certain files can only be fetched via a local referrer.
+The files have to be referenced by a local web page.
+If a web page on some other site references the files, that fetch will
+be blocked.
+There are three config-file variables for this feature:
+.TP
+.B urlpat
+A wildcard pattern for the URLs that should require a local referrer.
+This is typically just image files, sound files, and so on.
+For example:
+.nf
+ urlpat=**.jpg|**.gif|**.au|**.wav
+.fi
+For most sites, that one setting is all you need to enable referrer filtering.
+.TP
+.B noemptyreferrers
+By default, requests with no referrer at all, or a null referrer, or a
+referrer with no apparent hostname, are allowed.
+With this variable set, such requests are disallowed.
+.TP
+.B localpat
+A wildcard pattern that specifies the local host or hosts.
+This is used to determine if the host in the referrer is local or not.
+If not specified it defaults to the actual local hostname.
+.SH SYMLINKS
+.PP
+thttpd is very picky about symbolic links.
+Before delivering any file, it first checks each element in the path
+to see if it's a symbolic link, and expands them all out to get the final
+actual filename.
+Along the way it checks for things like links with ".." that go above
+the server's directory, and absolute symlinks (ones that start with a /).
+These are prohibited as security holes, so the server returns an
+error page for them.
+This means you can't set up your web directory with a bunch of symlinks
+pointing to individual users' home web directories.
+Instead you do it the other way around - the user web directories are
+real subdirs of the main web directory, and in each user's home
+dir there's a symlink pointing to their actual web dir.
+.PP
+The CGI pattern is also affected - it gets matched against the fully-expanded
+filename. So, if you have a single CGI directory but then put a symbolic
+link in it pointing somewhere else, that won't work. The CGI program will be
+treated as a regular file and returned to the client, instead of getting run.
+This could be confusing.
+.SH PERMISSIONS
+.PP
+thttpd is also picky about file permissions.
+It wants data files (HTML, images) to be world readable.
+Readable by the group that the thttpd process runs as is not enough - thttpd
+checks explicitly for the world-readable bit.
+This is so that no one ever gets surprised by a file that's not set
+world-readable and yet somehow is readable by the HTTP server and
+therefore the *whole* world.
+.PP
+The same logic applies to directories.
+As with the standard Unix "ls" program, thttpd will only let you
+look at the contents of a directory if its read bit is on; but
+as with data files, this must be the world-read bit, not just the
+group-read bit.
+.PP
+thttpd also wants the execute bit to be *off* for data files.
+A file that is marked executable but doesn't match the CGI pattern
+might be a script or program that got accidentally left in the
+wrong directory.
+Allowing people to fetch the contents of the file might be a security breach,
+so this is prohibited.
+Of course if an executable file *does* match the CGI pattern, then it
+just gets run as a CGI.
+.PP
+In summary, data files should be mode 644 (rw-r--r--),
+directories should be 755 (rwxr-xr-x) if you want to allow indexing and
+711 (rwx--x--x) to disallow it, and CGI programs should be mode
+755 (rwxr-xr-x) or 711 (rwx--x--x).
+.SH LOGS
+.PP
+thttpd does all of its logging via syslog(3).
+The facility it uses is configurable.
+Aside from error messages, there are only a few log entry types of interest,
+all fairly similar to CERN Common Log Format:
+.nf
+ Aug 6 15:40:34 acme thttpd[583]: 165.113.207.103 - - "GET /file" 200 357
+ Aug 6 15:40:43 acme thttpd[583]: 165.113.207.103 - - "HEAD /file" 200 0
+ Aug 6 15:41:16 acme thttpd[583]: referrer http://www.acme.com/ -> /dir
+ Aug 6 15:41:16 acme thttpd[583]: user-agent Mozilla/1.1N
+.fi
+The package includes a script for translating these log entries info
+CERN-compatible files.
+Note that thttpd does not translate numeric IP addresses into domain names.
+This is both to save time and as a minor security measure (the numeric
+address is harder to spoof).
+.PP
+Relevant config.h option: LOG_FACILITY.
+.PP
+If you'd rather log directly to a file, you can use the -l command-line
+flag. But note that error messages still go to syslog.
+.SH SIGNALS
+.PP
+thttpd handles a couple of signals, which you can send via the
+standard Unix kill(1) command:
+.TP
+.B INT,TERM
+These signals tell thttpd to shut down immediately.
+Any requests in progress get aborted.
+.TP
+.B USR1
+This signal tells thttpd to shut down as soon as it's done servicing
+all current requests.
+In addition, the network socket it uses to accept new connections gets
+closed immediately, which means a fresh thttpd can be started up
+immediately.
+.TP
+.B USR2
+This signal tells thttpd to generate the statistics syslog messages
+immediately, instead of waiting for the regular hourly update.
+.TP
+.B HUP
+This signal tells thttpd to close and re-open its (non-syslog) log file,
+for instance if you rotated the logs and want it to start using the
+new one.
+This is a little tricky to set up correctly, for instance if you are using
+chroot() then the log file must be within the chroot tree, but it's
+definitely doable.

+Geoff Adams, Dan Kegel, John Hascall, Bennett Todd, KIKUCHI Takahiro,

+.TH syslogtocern 8 "12 October 1995"
+.SH NAME
+syslogtocern - convert thttpd syslog entries into CERN Common Log format
+.SH SYNOPSIS
+.B syslogtocern
+.I logfile
+.RI ...
+.SH DESCRIPTION
+.PP
+Reads one or more syslog files as input.
+Takes the thttpd entries, and converts them into CERN Combined Common
+Log format.
+Produces two files as output: access_log and error_log.
+If files with those names already exist in the current directory, they
+are overwritten.
+.SH "SEE ALSO"
+thttpd(8)
+.SH "BUGS / DEFICIENCIES"
+Lumps all thttpd processes together.
+It ought to produce separate files for each, identified by IP address and
+port number.
+However, that change represents a huge increase in complexity, so next version.

+/* fdwatch.h - header file for fdwatch package
+**
+** This package abstracts the use of the select()/poll()/kqueue()
+** system calls. The basic function of these calls is to watch a set
+** of file descriptors for activity. select() originated in the BSD world,
+** while poll() came from SysV land, and their interfaces are somewhat
+** different. fdwatch lets you write your code to a single interface,
+** with the portability differences hidden inside the package.
+**
+** Usage is fairly simple. Call fdwatch_get_nfiles() to initialize
+** the package and find out how many fine descriptors are available.
+** Then each time through your main loop, call fdwatch_clear(), then
+** fdwatch_add_fd() for each of the descriptors you want to watch,
+** then call fdwatch() to actually perform the watch. After it returns
+** you can check which descriptors are ready via fdwatch_check_fd().
+**
+** If your descriptor set hasn't changed from the last time through
+** the loop, you can skip calling fdwatch_clear() and fdwatch_add_fd()
+** to save a little CPU time.

+.SH DESCRIPTION
+.PP
+.I thttpd
+is a simple, small, fast, and secure HTTP server.
+It doesn't have a lot of special features, but it suffices for most uses of
+the web, it's about as fast as the best full-featured servers (Apache, NCSA,
+Netscape),
+and it has one extremely useful feature (URL-traffic-based throttling)
+that no other server currently has.
+.SH OPTIONS
+.TP
+.B -C
+Specifies a config-file to read.
+All options can be set either by command-line flags or in the config file.
+See below for details.
+.TP
+.B -p
+Specifies an alternate port number to listen on.
+The default is 80.
+The config-file option name for this flag is "port",
+and the config.h option is DEFAULT_PORT.
+.TP
+.B -d
+Specifies a directory to chdir() to at startup.
+This is merely a convenience - you could just as easily
+do a cd in the shell script that invokes the program.
+The config-file option name for this flag is "dir",
+and the config.h options are WEBDIR, USE_USER_DIR.
+.TP
+.B -r
+Do a chroot() at initialization time, restricting file access
+to the program's current directory.
+If -r is the compiled-in default, then -nor disables it.
+See below for details.
+The config-file option names for this flag are "chroot" and "nochroot",
+and the config.h option is ALWAYS_CHROOT.
+.TP
+.B -dd
+Specifies a directory to chdir() to after chrooting.
+If you're not chrooting, you might as well do a single chdir() with
+the -d flag.
+If you are chrooting, this lets you put the web files in a subdirectory
+of the chroot tree, instead of in the top level mixed in with the
+chroot files.
+The config-file option name for this flag is "data_dir".
+.TP
+.B -nos
+Don't do explicit symbolic link checking.
+Normally, thttpd explicitly expands any symbolic links in filenames,
+to check that the resulting path stays within the original document tree.
+If you want to turn off this check and save some CPU time, you can use
+the -nos flag, however this is not recommended.
+Note, though, that if you are using the chroot option, the symlink
+checking is unnecessary and is turned off, so the safe way to save
+those CPU cycles is to use chroot.
+The config-file option names for this flag are "symlinkcheck" and "nosymlinkcheck".
+.TP
+.B -v
+Do el-cheapo virtual hosting.
+If -v is the compiled-in default, then -nov disables it.
+See below for details.
+The config-file option names for this flag are "vhost" and "novhost",
+and the config.h option is ALWAYS_VHOST.
+.TP
+.B -g
+Use a global passwd file.
+This means that every file in the entire document tree is protected by
+the single .htpasswd file at the top of the tree.
+Otherwise the semantics of the .htpasswd file are the same.
+If this option is set but there is no .htpasswd file in
+the top-level directory, then thttpd proceeds as if the option was
+not set - first looking for a local .htpasswd file, and if that doesn't
+exist either then serving the file without any password.
+If -g is the compiled-in default, then -nog disables it.
+The config-file option names for this flag are "globalpasswd" and
+"noglobalpasswd",
+and the config.h option is ALWAYS_GLOBAL_PASSWD.
+.TP
+.B -u
+Specifies what user to switch to after initialization when started as root.
+The default is "nobody".
+The config-file option name for this flag is "user",
+and the config.h option is DEFAULT_USER.
+.TP
+.B -c
+Specifies a wildcard pattern for CGI programs, for instance "**.cgi"
+or "/cgi-bin/*".
+See below for details.
+The config-file option name for this flag is "cgipat",
+and the config.h option is CGI_PATTERN.
+.TP
+.B -t
+Specifies a file of throttle settings.
+See below for details.
+The config-file option name for this flag is "throttles".
+.TP
+.B -h
+Specifies a hostname to bind to, for multihoming.
+The default is to bind to all hostnames supported on the local machine.
+See below for details.
+The config-file option name for this flag is "host",
+and the config.h option is SERVER_NAME.
+.TP
+.B -l
+Specifies a file for logging.
+If no -l argument is specified, thttpd logs via syslog().
+If "-l /dev/null" is specified, thttpd doesn't log at all.
+The config-file option name for this flag is "logfile".
+.TP
+.B -i
+Specifies a file to write the process-id to.
+If no file is specified, no process-id is written.
+You can use this file to send signals to thttpd.
+See below for details.
+The config-file option name for this flag is "pidfile".
+.TP
+.B -T
+Specifies the character set to use with text MIME types.
+The default is UTF-8.
+The config-file option name for this flag is "charset",
+and the config.h option is DEFAULT_CHARSET.
+.TP
+.B -P
+Specifies a P3P server privacy header to be returned with all responses.
+See http://www.w3.org/P3P/ for details.
+Thttpd doesn't do anything at all with the string except put it in the
+P3P: response header.
+The config-file option name for this flag is "p3p".
+.TP
+.B -M
+Specifies the number of seconds to be used in a "Cache-Control: max-age"
+header to be returned with all responses.
+An equivalent "Expires" header is also generated.
+The default is no Cache-Control or Expires headers,
+which is just fine for most sites.
+The config-file option name for this flag is "max_age".
+.TP
+.B -V
+Shows the current version info.
+.TP
+.B -D
+This was originally just a debugging flag, however it's worth mentioning
+because one of the things it does is prevent thttpd from making itself
+a background daemon.
+Instead it runs in the foreground like a regular program.
+This is necessary when you want to run thttpd wrapped in a little shell
+script that restarts it if it exits.
+.SH "CONFIG-FILE"
+.PP
+All the command-line options can also be set in a config file.
+One advantage of using a config file is that the file can be changed,
+and thttpd will pick up the changes with a restart.
+.PP
+The syntax of the config file is simple, a series of "option" or
+"option=value" separated by whitespace.
+The option names are listed above with their corresponding command-line flags.
+.SH "CHROOT"
+.PP
+chroot() is a system call that restricts the program's view
+of the filesystem to the current directory and directories
+below it.
+It becomes impossible for remote users to access any file
+outside of the initial directory.
+The restriction is inherited by child processes, so CGI programs get it too.
+This is a very strong security measure, and is recommended.
+The only downside is that only root can call chroot(), so this means
+the program must be started as root.
+However, the last thing it does during initialization is to
+give up root access by becoming another user, so this is safe.
+.PP
+The program can also be compile-time configured to always
+do a chroot(), without needing the -r flag.
+.PP
+Note that with some other web servers, such as NCSA httpd, setting
+up a directory tree for use with chroot() is complicated, involving
+creating a bunch of special directories and copying in various files.
+With thttpd it's a lot easier, all you have to do is make sure
+any shells, utilities, and config files used by your CGI programs and
+scripts are available.
+If you have CGI disabled, or if you make a policy that all CGI programs
+must be written in a compiled language such as C and statically linked,
+then you probably don't have to do any setup at all.
+.PP
+However, one thing you should do is tell syslogd about the chroot tree,
+so that thttpd can still generate syslog messages.
+Check your system's syslodg man page for how to do this.
+In FreeBSD you would put something like this in /etc/rc.conf:
+.nf
+ syslogd_flags="-l /usr/local/www/data/dev/log"
+.fi
+Substitute in your own chroot tree's pathname, of course.
+Don't worry about creating the log socket, syslogd wants to do that itself.
+(You may need to create the dev directory.)
+In Linux the flag is -a instead of -l, and there may be other differences.
+.PP
+Relevant config.h option: ALWAYS_CHROOT.
+.SH "CGI"
+.PP
+thttpd supports the CGI 1.1 spec.
+.PP
+In order for a CGI program to be run, its name must match the pattern
+specified either at compile time or on the command line with the -c flag.
+This is a simple shell-style filename pattern.
+You can use * to match any string not including a slash,
+or ** to match any string including slashes,
+or ? to match any single character.
+You can also use multiple such patterns separated by |.
+The patterns get checked against the filename
+part of the incoming URL.
+Don't forget to quote any wildcard characters so that the shell doesn't
+mess with them.
+.PP
+Restricting CGI programs to a single directory lets the site administrator
+review them for security holes, and is strongly recommended.
+If there are individual users that you trust, you can enable their
+directories too.
+.PP
+If no CGI pattern is specified, neither here nor at compile time,
+then CGI programs cannot be run at all.
+If you want to disable CGI as a security measure, that's how you do it, just
+comment out the patterns in the config file and don't run with the -c flag.
+.PP
+Note: the current working directory when a CGI program gets run is
+the directory that the CGI program lives in.
+This isn't in the CGI 1.1 spec, but it's what most other HTTP servers do.
+.PP
+Relevant config.h options: CGI_PATTERN, CGI_TIMELIMIT, CGI_NICE, CGI_PATH, CGI_LD_LIBRARY_PATH, CGIBINDIR.
+.SH "BASIC AUTHENTICATION"
+.PP
+Basic Authentication is available as an option at compile time.
+If enabled, it uses a password file in the directory to be protected,
+called .htpasswd by default.
+This file is formatted as the familiar colon-separated
+username/encrypted-password pair, records delimited by newlines.
+The protection does not carry over to subdirectories.
+The utility program htpasswd(1) is included to help create and
+modify .htpasswd files.
+.PP
+Relevant config.h option: AUTH_FILE
+.SH "THROTTLING"
+.PP
+The throttle file lets you set maximum byte rates on URLs or URL groups.
+You can optionally set a minimum rate too.
+The format of the throttle file is very simple.
+A # starts a comment, and the rest of the line is ignored.
+Blank lines are ignored.
+The rest of the lines should consist of a pattern, whitespace, and a number.
+The pattern is a simple shell-style filename pattern, using ?/**/*, or
+multiple such patterns separated by |.
+.PP
+The numbers in the file are byte rates, specified in units of bytes per second.
+For comparison, a v.90 modem gives about 5000 B/s depending on compression,
+a double-B-channel ISDN line about 12800 B/s, and a T1 line is about
+150000 B/s.
+If you want to set a minimum rate as well, use number-number.
+.PP
+Example:
+.nf
+ # throttle file for www.acme.com
+
+ ** 2000-100000 # limit total web usage to 2/3 of our T1,
+ # but never go below 2000 B/s
+ **.jpg|**.gif 50000 # limit images to 1/3 of our T1
+ **.mpg 20000 # and movies to even less
+ jef/** 20000 # jef's pages are too popular
+.fi
+.PP
+Throttling is implemented by checking each incoming URL filename against all
+of the patterns in the throttle file.
+The server accumulates statistics on how much bandwidth each pattern
+has accounted for recently (via a rolling average).
+If a URL matches a pattern that has been exceeding its specified limit,
+then the data returned is actually slowed down, with
+pauses between each block.
+If that's not possible (e.g. for CGI programs) or if the bandwidth has gotten
+way larger than the limit, then the server returns a special code
+saying 'try again later'.
+.PP
+The minimum rates are implemented similarly.
+If too many people are trying to fetch something at the same time,
+throttling may slow down each connection so much that it's not really
+useable.
+Furthermore, all those slow connections clog up the server, using
+up file handles and connection slots.
+Setting a minimum rate says that past a certain point you should not
+even bother - the server returns the 'try again later" code and the
+connection isn't even started.
+.PP
+There is no provision for setting a maximum connections/second throttle,
+because throttling a request uses as much cpu as handling it, so
+there would be no point.
+There is also no provision for throttling the number of simultaneous
+connections on a per-URL basis.
+However you can control the overall number of connections for the whole
+server very simply, by setting the operating system's per-process file
+descriptor limit before starting thttpd.
+Be sure to set the hard limit, not the soft limit.
+.SH "MULTIHOMING"
+.PP
+Multihoming means using one machine to serve multiple hostnames.
+For instance, if you're an internet provider and you want to let
+all of your customers have customized web addresses, you might
+have www.joe.acme.com, www.jane.acme.com, and your own www.acme.com,
+all running on the same physical hardware.
+This feature is also known as "virtual hosts".
+There are three steps to setting this up.
+.PP
+One, make DNS entries for all of the hostnames.
+The current way to do this, allowed by HTTP/1.1, is to use CNAME aliases,
+like so:
+.nf
+ www.acme.com IN A 192.100.66.1
+ www.joe.acme.com IN CNAME www.acme.com
+ www.jane.acme.com IN CNAME www.acme.com
+.fi
+However, this is incompatible with older HTTP/1.0 browsers.
+If you want to stay compatible, there's a different way - use A records
+instead, each with a different IP address, like so:
+.nf
+ www.acme.com IN A 192.100.66.1
+ www.joe.acme.com IN A 192.100.66.200
+ www.jane.acme.com IN A 192.100.66.201
+.fi
+This is bad because it uses extra IP addresses, a somewhat scarce resource.
+But if you want people with older browsers to be able to visit your
+sites, you still have to do it this way.
+.PP
+Step two.
+If you're using the modern CNAME method of multihoming, then you can
+skip this step.
+Otherwise, using the older multiple-IP-address method you
+must set up IP aliases or multiple interfaces for the extra addresses.
+You can use ifconfig(8)'s alias command to tell the machine to answer to
+all of the different IP addresses.
+Example:
+.nf
+ ifconfig le0 www.acme.com
+ ifconfig le0 www.joe.acme.com alias
+ ifconfig le0 www.jane.acme.com alias
+.fi
+If your OS's version of ifconfig doesn't have an alias command, you're
+probably out of luck (but see http://www.acme.com/software/thttpd/notes.html).
+.PP
+Third and last, you must set up thttpd to handle the multiple hosts.
+The easiest way is with the -v flag, or the ALWAYS_VHOST config.h option.
+This works with either CNAME multihosting or multiple-IP multihosting.
+What it does is send each incoming request to a subdirectory based on the
+hostname it's intended for.
+All you have to do in order to set things up is to create those subdirectories
+in the directory where thttpd will run.
+With the example above, you'd do like so:
+.nf
+ mkdir www.acme.com www.joe.acme.com www.jane.acme.com
+.fi
+If you're using old-style multiple-IP multihosting, you should also create
+symbolic links from the numeric addresses to the names, like so:
+.nf
+ ln -s www.acme.com 192.100.66.1
+ ln -s www.joe.acme.com 192.100.66.200
+ ln -s www.jane.acme.com 192.100.66.201
+.fi
+This lets the older HTTP/1.0 browsers find the right subdirectory.
+.PP
+There's an optional alternate step three if you're using multiple-IP
+multihosting: run a separate thttpd process for each hostname, using
+the -h flag to specify which one is which.
+This gives you more flexibility, since you can run each of these processes
+in separate directories, with different throttle files, etc.
+Example:
+.nf
+ thttpd -r -d /usr/www -h www.acme.com
+ thttpd -r -d /usr/www/joe -u joe -h www.joe.acme.com
+ thttpd -r -d /usr/www/jane -u jane -h www.jane.acme.com
+.fi
+But remember, this multiple-process method does not work with CNAME
+multihosting - for that, you must use a single thttpd process with
+the -v flag.
+.SH "CUSTOM ERRORS"
+.PP
+thttpd lets you define your own custom error pages for the various
+HTTP errors.
+There's a separate file for each error number, all stored in one
+special directory.
+The directory name is "errors", at the top of the web directory tree.
+The error files should be named "errNNN.html", where NNN is the error number.
+So for example, to make a custom error page for the authentication failure
+error, which is number 401, you would put your HTML into the file
+"errors/err401.html".
+If no custom error file is found for a given error number, then the
+usual built-in error page is generated.
+.PP
+If you're using the virtual hosts option, you can also have different
+custom error pages for each different virtual host.
+In this case you put another "errors" directory in the top of that
+virtual host's web tree.
+thttpd will look first in the virtual host errors directory, and
+then in the server-wide errors directory, and if neither of those
+has an appropriate error file then it will generate the built-in error.
+.SH "NON-LOCAL REFERRERS"
+.PP
+Sometimes another site on the net will embed your image files in their
+HTML files, which basically means they're stealing your bandwidth.
+You can prevent them from doing this by using non-local referrer filtering.
+With this option, certain files can only be fetched via a local referrer.
+The files have to be referenced by a local web page.
+If a web page on some other site references the files, that fetch will
+be blocked.
+There are three config-file variables for this feature:
+.TP
+.B urlpat
+A wildcard pattern for the URLs that should require a local referrer.
+This is typically just image files, sound files, and so on.
+For example:
+.nf
+ urlpat=**.jpg|**.gif|**.au|**.wav
+.fi
+For most sites, that one setting is all you need to enable referrer filtering.
+.TP
+.B noemptyreferrers
+By default, requests with no referrer at all, or a null referrer, or a
+referrer with no apparent hostname, are allowed.
+With this variable set, such requests are disallowed.
+.TP
+.B localpat
+A wildcard pattern that specifies the local host or hosts.
+This is used to determine if the host in the referrer is local or not.
+If not specified it defaults to the actual local hostname.
+.SH SYMLINKS
+.PP
+thttpd is very picky about symbolic links.
+Before delivering any file, it first checks each element in the path
+to see if it's a symbolic link, and expands them all out to get the final
+actual filename.
+Along the way it checks for things like links with ".." that go above
+the server's directory, and absolute symlinks (ones that start with a /).
+These are prohibited as security holes, so the server returns an
+error page for them.
+This means you can't set up your web directory with a bunch of symlinks
+pointing to individual users' home web directories.
+Instead you do it the other way around - the user web directories are
+real subdirs of the main web directory, and in each user's home
+dir there's a symlink pointing to their actual web dir.
+.PP
+The CGI pattern is also affected - it gets matched against the fully-expanded
+filename. So, if you have a single CGI directory but then put a symbolic
+link in it pointing somewhere else, that won't work. The CGI program will be
+treated as a regular file and returned to the client, instead of getting run.
+This could be confusing.
+.SH PERMISSIONS
+.PP
+thttpd is also picky about file permissions.
+It wants data files (HTML, images) to be world readable.
+Readable by the group that the thttpd process runs as is not enough - thttpd
+checks explicitly for the world-readable bit.
+This is so that no one ever gets surprised by a file that's not set
+world-readable and yet somehow is readable by the HTTP server and
+therefore the *whole* world.
+.PP
+The same logic applies to directories.
+As with the standard Unix "ls" program, thttpd will only let you
+look at the contents of a directory if its read bit is on; but
+as with data files, this must be the world-read bit, not just the
+group-read bit.
+.PP
+thttpd also wants the execute bit to be *off* for data files.
+A file that is marked executable but doesn't match the CGI pattern
+might be a script or program that got accidentally left in the
+wrong directory.
+Allowing people to fetch the contents of the file might be a security breach,
+so this is prohibited.
+Of course if an executable file *does* match the CGI pattern, then it
+just gets run as a CGI.
+.PP
+In summary, data files should be mode 644 (rw-r--r--),
+directories should be 755 (rwxr-xr-x) if you want to allow indexing and
+711 (rwx--x--x) to disallow it, and CGI programs should be mode
+755 (rwxr-xr-x) or 711 (rwx--x--x).
+.SH LOGS
+.PP
+thttpd does all of its logging via syslog(3).
+The facility it uses is configurable.
+Aside from error messages, there are only a few log entry types of interest,
+all fairly similar to CERN Common Log Format:
+.nf
+ Aug 6 15:40:34 acme thttpd[583]: 165.113.207.103 - - "GET /file" 200 357
+ Aug 6 15:40:43 acme thttpd[583]: 165.113.207.103 - - "HEAD /file" 200 0
+ Aug 6 15:41:16 acme thttpd[583]: referrer http://www.acme.com/ -> /dir
+ Aug 6 15:41:16 acme thttpd[583]: user-agent Mozilla/1.1N
+.fi
+The package includes a script for translating these log entries info
+CERN-compatible files.
+Note that thttpd does not translate numeric IP addresses into domain names.
+This is both to save time and as a minor security measure (the numeric
+address is harder to spoof).
+.PP
+Relevant config.h option: LOG_FACILITY.
+.PP
+If you'd rather log directly to a file, you can use the -l command-line
+flag. But note that error messages still go to syslog.
+.SH SIGNALS
+.PP
+thttpd handles a couple of signals, which you can send via the
+standard Unix kill(1) command:
+.TP
+.B INT,TERM
+These signals tell thttpd to shut down immediately.
+Any requests in progress get aborted.
+.TP
+.B USR1
+This signal tells thttpd to shut down as soon as it's done servicing
+all current requests.
+In addition, the network socket it uses to accept new connections gets
+closed immediately, which means a fresh thttpd can be started up
+immediately.
+.TP
+.B USR2
+This signal tells thttpd to generate the statistics syslog messages
+immediately, instead of waiting for the regular hourly update.
+.TP
+.B HUP
+This signal tells thttpd to close and re-open its (non-syslog) log file,
+for instance if you rotated the logs and want it to start using the
+new one.
+This is a little tricky to set up correctly, for instance if you are using
+chroot() then the log file must be within the chroot tree, but it's
+definitely doable.
