Apache HTTP Server Version 2.2

Per-user web directories
On systems with multiple users, each user can be permitted to have a
    web site in their home directory using the UserDir directive. Visitors
    to a URL http://example.com/~username/ will get content
    out of the home directory of the user "username", out of
    the subdirectory specified by the UserDir directive.

Setting the file path with UserDir
The UserDir
    directive specifies a directory out of which per-user
    content is loaded. This directive may take several different forms.
If a path is given which does not start with a leading slash, it is assumed to be a directory path relative to the home directory of the specified user. Given this configuration:
      UserDir public_html
    
the URL http://example.com/~rbowen/file.html will be
    translated to the file path
    /home/rbowen/public_html/file.html
If a path is given starting with a slash, a directory path will be constructed using that path, plus the username specified. Given this configuration:
      UserDir /var/html
    
the URL http://example.com/~rbowen/file.html will be
    translated to the file path /var/html/rbowen/file.html
If a path is provided which contains an asterisk (*), a path is used in which the asterisk is replaced with the username. Given this configuration:
      UserDir /var/www/*/docs
    
the URL http://example.com/~rbowen/file.html will be
    translated to the file path
    /var/www/rbowen/docs/file.html
Multiple directories or directory paths can also be set.
      UserDir public_html /var/html
    
For the URL http://example.com/~rbowen/file.html, 
    Apache will search for ~rbowen. If it isn't found, 
    Apache will search for rbowen in /var/html. If
    found, the above URL will then be translated to the file path 
    /var/html/rbowen/file.html
Redirecting to external URLs
The UserDir directive can be
      used to redirect user directory requests to external URLs.
      UserDir http://example.org/users/*/
    
The above example will redirect a request for
    http://example.com/~bob/abc.html to
    http://example.org/users/bob/abc.html.
Restricting what users are permitted to use this feature
Using the syntax shown in the UserDir documentation, you can restrict what users are permitted to use this functionality:
      UserDir disabled root jro fish
    
The configuration above will enable the feature for all users
    except for those listed in the disabled statement.
    You can, likewise, disable the feature for all but a few users by
    using a configuration like the following:
      UserDir disabled
      UserDir enabled rbowen krietz
    
See UserDir
    documentation for additional examples.
Enabling a cgi directory for each user
In order to give each user their own cgi-bin directory, you can use
    a <Directory>
    directive to make a particular subdirectory of a user's home directory
    cgi-enabled.
      <Directory /home/*/public_html/cgi-bin/>
       Options ExecCGI
       SetHandler cgi-script
       </Directory>
    
Then, presuming that UserDir is set to
    public_html, a cgi program example.cgi
    could be loaded from that directory as:
    http://example.com/~rbowen/cgi-bin/example.cgi
    
Allowing users to alter configuration
If you want to allows users to modify the server configuration in
    their web space, they will need to use .htaccess files to
    make these changed. Ensure that you have set AllowOverride to a
    value sufficient for the directives that you want to permit the users
    to modify. See the .htaccess tutorial for
    additional details on how this works.
