CGI::Untaint::url - validate a URL
use CGI::Untaint; my $handler = CGI::Untaint->new($q->Vars); my $url = $handler->extract(-as_url => 'web_address');
This Input Handler verifies that it is dealing with a reasonable URL. This mostly means that it will find the first thing that looks like a URL in your input, where by "looks like", we mean anything that URI::URL thinks is sensible, (with some tweaks, courtesy of URI::Find::Schemeless::Stricter), so it will accept any of (for example):
http://c2.com/cgi/wiki www.tmtm.com See: http://www.redmeat.com/redmeat/1996-09-30/ [http://www.angelfire.com/la/carlosmay/Tof.html] ftp://ftp.ftp.org/
The resulting value will be a URI::URL object.
