lol, I didn't asked someone to write it for me. I just asked if someone has an already made function since I have been committed three works to do and I don't have a lot of time. :) Copy and paste isn't really all that hard don't you think?<BR><BR>Anyway, I was searching for a function to see if the url is correctly formatted. The url is picked by a form. I wasn't talking about custom error pages.
