This code snippet uses URI package to convert relative URLs contained in HTTP::Response objects (generated by LWP::UserAgent or WWW::Mechanize) to absolute URLs. Useful for CGI scripts that act as a proxy between the browser and website.
use LWP::UserAgent;
use URI;

my $response = LWP::UserAgent->new->get('http://search.cpan.org/');

$html = $response->content;
$base = $response->base;

# RegEx converts all links in $html to absolute URLs
$html =~ s/<(.*?)(href|src|action|background)\s*=\s*("|'?)(.*?)\3((\s+
+.*?)*)>/"<".$1.$2."=\"".URI->new_abs($4,$base)->as_string."\"".$5.">"
+/eigs;

print $html;
