^(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!
