See gitweb/README:

 * $my_url, $my_uri
   Full URL and absolute URL of gitweb script;
   in earlier versions of gitweb you might have need to set those
   variables, now there should be no need to do it.

Or you can set up $base_url in your gitweb configuration file (which
is not mentioned in the gitweb/README, unfortunately).


Since 81d3fe9 (gitweb: fix wrong base URL when non-root DirectoryIndex)
by Giuseppe Bilotta (I have CC-ed him) gitweb tries to set $base_url
using $cgi->url(-base => 1) . $ENV{'SCRIPT_NAME'} if we use $path_info,
and if both $my_url and $my_uri begin with $path_info.

I do not know CGI.pm well enough to think up a better solution, but
when $base_url was introduced I have posted email on git mailing list
about slight mismatch between what CGI.pm thinks as absolute URL and
the notion of absolute URL and absolute _paths_ in appropriate RFC,
see e.g. 
  http://thread.gmane.org/gmane.comp.version-control.git/107344/focus=107437
  http://thread.gmane.org/gmane.comp.version-control.git/107898/focus=108010

P.S. I didn't look at the site in question.
