Title: Port numbers not allowed

Comment:
This expression fails to match a url with a port number specification. For example, http://www.mydomain:8080/somedir will fail

The pattern by John Main does not match anything after a ?, so any querystring will be lopped off. Use the original with the additional suggestions by Brian and Neik (assuming you do an HtmlEncode() on the string before matching)...

If you use this with URL's with entities, change & to (&)
