Why does the below code fail when the url is "http://www.go.com"? Infact, every URL I try to put in there errors out.

if ($url !~ /^http\:/i || $url !~ /^ftp:/i || $url !~ /^file:/i || $u +rl !~ /^mailto:/i || $url !~ /^telnet:/i) { print header; print "<html><head><title>Malformed URL</title>"; print qq(<meta http-equiv="refresh" content="4;url=$redirect_url">< +/head><body>); print "<b>Malformed URL</b><p>You will be redirected to our main pa +ge in 4 seconds. Your url was: $url"; print "</body></html>"; exit; }
