Here you go
#!/usr/bin/perl -w
use strict;

use URI::Escape;
use HTTP::Request;

my $ru = uri_escape("http://foo.org/cgi-bin/bar.cgi?baz = qu ux;foo=di
+m");

my $v=new HTTP::Request(url=>"http://foo.org/cgi-bin/bar.cgi?ru=$ru");
print $v->url, $/;

=pod

prints:
http://foo.org/cgi-bin/bar.cgi?ru=http%3A%2F%2Ffoo.org%2Fcgi-bin%2Fbar
+.cgi%3Fbaz%20%3D%20qu%20ux%3Bfoo%3Ddim

call, say:
$cgi->redirect( uri_unescape($cgi->param('ru'));
to use the url
=cut

Update: I hasten to point out the the uri_unescape() suggestion in pod is insecure if you care where the redirect goes or whether it is an url at all. Repaired a couple of pasteos.
