^(http|https|ftp)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~])*$
Description
Modified URL RegExp that requires (http, https, ftp)://, A nice domain, and a decent file/folder string. Allows : after domain name, and these characters in the file/folder sring (letter, numbers, - . _ ? , ' / \ + & % $ # = ~). Blocks all other special characters-good for protecting against user input!
Matches
http://www.blah.com/~joe | ftp://ftp.blah.co.uk:2828/blah%20blah.gif | https://blah.gov/blah-blah.as
Non-Matches
www.blah.com | http://www.blah"blah.com/I have spaces! | ftp://blah_underscore/[nope]

I found this addition usefull, as it also allows localhost urls: ^(http|https|ftp)\://(([a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*))|localhost)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&amp;%\$#\=~])*$


Title: A bit out of date.

A good regex, but it's a little out of date. Now there are domain names with other than two or three characters in the top level domain, such as .info/.aero/.coop You could include a list of these domains or you could just be permissive and allow the top level domain to be any combination of more than one letter.
