By the way, I have thought that it would conflict with use path_info for 'blob_plain' action to have links work in document... but I forgot that then we do not use gitweb HTML header...

Errrr... I think you are talking about _full_ vs. _absolute_, not _absolute_ vs. _relative_, see below.

our $my_url = $cgi->url(); # = $cgi->url(-full);
our $my_uri = $cgi->url(-absolute => 1);

our $path_info = $ENV{"PATH_INFO"};
if ($path_info) {
$my_url =~ s,\Q$path_info\E$,,;
$my_uri =~ s,\Q$path_info\E$,,;
}and if BASE is a document, then relative URLs are resolved using
dirname of BASE, I guess, as
http://www.w3.org/TR/html401/struct/links.html#edef-BASE
contains in example:
<BASE href="http://www.aviary.com/products/intro.html">
See also RFC1808 (Relative Uniform Resource Locators), section
4. Resolving Relative URLs:
Step 6: The last segment of the base URL's path (anything
following the rightmost slash "/", or the entire path if no
slash is present) is removed and the embedded URL's path is
appended in its place.[...]Besides, if you strip SCRIPT_NAME, then you are left with document root; this means that if git-logo.png etc. are in the same directory as gitweb.cgi, they won't be found. For example for me it doesn't work correctly (I have git-logo.png along gitweb.cgi, which is in /cgi-bin/gitweb/... and thanks to symlinks also in /gitweb/).
By the way, according to documentation $cgi->url() should *not* contain path_info; you have to use $cgi->url(-path_info=>1) for that... strange.

Just in case, to be compatible with both XHML and HTML, we should use
+ print "<base href=\"$base\" />\n";
...if not for the fact that surrounding code doesn't use this way...
