** a simple shell-style filename pattern, with ? and *, or multiple such
** patterns separated by |.  The patterns get checked against the filename
** part of the incoming URL.
**
** 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.
**
** You can also specify a CGI pattern on the command line, with the -c flag.
** Such a pattern overrides this compiled-in default.
**
** If no CGI pattern is specified, neither here nor on the command line,
** 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 don't define any
** pattern here and don't run with the -c flag.

/* CONFIGURE: Tilde mapping.  Many URLs use ~username to indicate a

** this construct to an actual filename.
**
** 1) Map ~username to <prefix>/username.  This is the recommended choice.
** Each user gets a subdirectory in the main chrootable web tree, and
** the tilde construct points there.  The prefix could be something
** like "users", or it could be empty.  See also the makeweb program
** for letting users create their own web subdirectories.
**
** 2) Map ~username to <user's homedir>/<postfix>.  The postfix would be
** the name of a subdirectory off of the user's actual home dir, something
** like "public_html".  This is what NCSA and other servers do.  The problem
** is, you can't do this and chroot() at the same time, so it's inherently
** a security hole.  This is strongly dis-recommended, but it's here because
** some people really want it.  Use at your own risk.
**
** You can also leave both options undefined, and thttpd will not do
** anything special about tildes.  Enabling both options is an error.

** machines, and want to build in alternate names for some or all of
** them, you can define a list of canonical name to altername name
** mappings.  thttpd seatches the list and when it finds a match on
** the canonical name, that alternate name gets used.  If no match
** is found, the canonical name gets used.
**
** If both SERVER_NAME and SERVER_NAME_LIST are defined here, thttpd searches
** the list as above, and if no match is found then SERVER_NAME gets used.
**
** In any case, if thttpd is started with the -h flag, that name always
