http & www / subdomain check

Expression |
^(http\://){1}(((www\.){1}([a-zA-Z0-9\-]*\.){1,}){1}|([a-zA-Z0-9\-]*\.){1,10}){1}([a-zA-Z]{2,6}\.){1}([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~])* |
Description |
This checks to see if a URL has http:// in it, and if it has either www or a subdomain before the domain and tld. Without (http\://) it only does the latter check. Replace http by (http|https|ftp) for other protocols. Still not happy about this: http://www.www.passshouldfail.com |
