Matching a web address through regex

Question

I want to match a web address through regex which should capture http://www.google.com as well as www.google.com i.e. with and without protocol.

Did you mean to match specific domain names (e.g. google), or do you need to match arbitrary domain names? — Zach Scrivena

Well it's going to depend on exactly what you want to capture ("FTP"? "/index.htm"?) because a general URI capture based on the RFC standard is very hard, but you could start with:

/^((https?\:\/\/)?([\w\d\-]+\.){2,}([\w\d]{2,})((\/[\w\d\-\.]+)*(\/[\w\d\-]+\.[\w\d]{3,4}(\?.*)?)?)?)$/

Complicated see?
