For this you use {{mod_rewrite}}.

!! Example

In your 000-default file, for apache put

{{{
RewriteEngine on
RewriteRule ^/gitweb/([a-zA-Z0-9_\-]+\.git)/?(\?.*)?$ /cgi/bin/gitweb.cgi/$1 [PT]
RewriteCond %{HTTP_USER_AGENT} !FeedBurner
RewriteRule ^/dsawiki/rss\.rdf$ http://feeds.feedburner.com/dsawiki [R]
RewriteRule ^/foobar$ http://host.domain.com:8100/admin [R]
RewriteRule ^/$ /dsawiki [R]

Alias /gitweb /var/path/to/git/repos
}}}

!! Explanations

! RewriteEngine on

The first line enables mod_rewrite.  You also must put it in mods-enabled.  See apache docs for this.

! Gitweb

The second line (RewriteRule) allows you to use {{http://host.domain.com/gitweb/}} to point to your repositories.  The {{Alias}} line at the bottom is also needed.

This line ends in {{{[PT]}}} which stands for "passthrough" (pass through to next handler).  It enables post-processing of the output of {{RewriteRule}} directives using {{Alias}}, {{ScriptAlias}}, and {{Redirect}}.

! RewriteCond HTTP_USER_AGENT

This line prevents the next line from operating if the HTTP_USER_AGENT is FeedBurner.  Basically, if you subscribe to my blog, you actually subscribe through FeedBurner.  I of course don't want FeedBurner getting forwarded back to itself.

! RewriteRule dsawiki/rss

If you are not FeedBurner, then any requests to {{/dsawiki/rss.rdf}} get forwarded to FeedBurner.  This ends in {{{[R]}}} because that's the end of the rule.

! RewriteRule /foobar

Going to {{http://host.mydomain.com/foobar}} will redirect to {{http://host.domain.com:8100.admin}}.  This is so people can go to a meaningful url instead of a port and /admin to see a Django admin panel.

! RewriteRule /dsawiki

This line forwards requests from {{http://domain.com}} to {{http://domain.com/dsawiki}}
