This sounds exactly like what I need to do... But say when the output comes, the URL doesn't have the name-value pairs appended to the end? Are they hidden there (maybe GET wasn't chosen)? How can I remove them in this case?

Thanks a lot, I guess one troublesome aspect is I am not in charge of the HTML stuff, so I'm working only on the CGI script.

Perhaps a combo of fetching the parameters and delete() will work?
