Apache Module mod_userdir
Summary
This module allows user-specific directories to be accessed using the
http://example.com/~user/ syntax.

    The UserDir directive sets the real
    directory in a user's home directory to use when a request for a
    document for a user is received. Directory-filename is
    one of the following:
    
      - The name of a directory or a pattern such as those shown
      below.
- The keyword disabled. This turns off
      all username-to-directory translations except those
      explicitly named with theenabledkeyword (see
      below).
- The keyword disabledfollowed by a
      space-delimited list of usernames. Usernames that appear in
      such a list will never have directory translation
      performed, even if they appear in anenabledclause.
- The keyword enabledfollowed by a
      space-delimited list of usernames. These usernames will have
      directory translation performed even if a global disable is
      in effect, but not if they also appear in adisabledclause.
If neither the enabled nor the
    disabled keywords appear in the
    Userdir directive, the argument is treated as a
    filename pattern, and is used to turn the name into a directory
    specification. A request for
    http://www.foo.com/~bob/one/two.html will be
    translated to:
| UserDir directive used | Translated path | 
|---|
| UserDir public_html | ~bob/public_html/one/two.html | 
| UserDir /usr/web | /usr/web/bob/one/two.html | 
| UserDir /home/*/www | /home/bob/www/one/two.html | 
    The following directives will send redirects to the client:
 
| UserDir directive used | Translated path | 
|---|
| UserDir http://www.foo.com/users | http://www.foo.com/users/bob/one/two.html | 
| UserDir
http://www.foo.com/*/usr | http://www.foo.com/bob/usr/one/two.html | 
| UserDir
http://www.foo.com/~*/ | http://www.foo.com/~bob/one/two.html | 
 
      Be careful when using this directive; for instance,
      "UserDir ./" would map "/~root" to
      "/" - which is probably undesirable. It is strongly
      recommended that your configuration include a "UserDir
      disabled root" declaration.  See also the Directory directive and the Security Tips page for
      more information.
 
Additional examples:
To allow a few users to have UserDir directories, but
not anyone else, use the following:
UserDir disabled
UserDir enabled user1 user2 user3
To allow most users to have UserDir directories, but
deny this to a few, use the following:
UserDir enabled
UserDir disabled user4 user5 user6
It is also possible to specify alternative user directories.
If you use a command like:
Userdir public_html /usr/web http://www.foo.com/
With a request for http://www.foo.com/~bob/one/two.html, will try to 
find the page at ~bob/public_html/one/two.html first, then
/usr/web/bob/one/two.html, and finally it will send a redirect
to http://www.foo.com/bob/one/two.html.
If you add a redirect, it must be the last alternative in the list.
Apache cannot determine if the redirect succeeded or not, so if you have
the redirect earlier in the list, that will always be the alternative
that is used.
