What is the regex to match a url?

Question

The regex should match a full url. think about port, parameters and special characters.
e.g. http://www.787.com:80/?test1=value%20two?something=more

if you can point me to a url that contains the regex (some regex collection) would be best.

I asked a question earlier on a similar subject without much response perhaps some of the links I found might help you:

Answer 2

On a lark (I don't use regex that often) I can think of:

(http\:\/\/\S+)\s+

That should be enough since URL can't have space in its midst, is \s stands for blank space? Saved the match to $1 by the pair of ().
