Regular Expression Details

Title Test Find Pattern Title
Version 1.3.0: I needed a regexp to validate URL's without the ht(f)tp(s):// and include North American domains (like .us and .ca) and there didn't seem to be one I created one. It will also work with ASP QueryStrings and anchor URL's. If you have a problem with the expression or have any suggestions to improve, please write me and let me know. Added .uk domain and expression now allows for URLs that contain JSP session IDs. 4/14/04 - added ability to include URLs that start with server names.

Colonel, In order to use the .ru domain, just add "|ru" (without quotes) after "|uk" in the RegEx. If you need any other assistance, let me know.

It should already validate on all of those. What URL are you testing with? I just did a test here at the site and all three (http://, ftp://, https://) worked for me.

Worked very well for me.
