Id change your regex firstly to test if http or not. Like so `/(http(s?):\/\/?).../` im on my phone so if anything is messed up im sorry but others will get my drift. — EasyBB, Jul 09 '14 at 07:16

Updated version - tested

^((https?|s?ftp):\/\/)?(((([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]))|((([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9]|[A-Za-z0-9][A-Za-z0-9\-]*[A-Za-z0-9])))(:[1-9][0-9]+)?(\/)?([/?].+)?$

Only two fails (for now :))

http://localhost:51932/default.aspx
https://192.168.0.25:5132/default.aspx
www.google.com
http://www.google.com
mailto:somebody@google.com                         // fail
somebody@google.com                                // fail 
www.url-with-querystring.com/?url=has-querystring
http://www.xxx.events
sftp://ftp.something.com
www.google.co.in
www.xxx.com
