Yes, thanks John, with a little tweaking this does just what I needed. I keep forgetting to use that compact conditional syntax, it's sexy.
I had to use PHP_SELF instead of REQUEST_URI first, since the latter contains the path, the script, and the query string. $url = $_SERVER['PHP_SELF'] . '?' . @$_SERVER['QUERY_STRING'] . '&newVar=1'; Now I can just throw in a conditional like below to make sure I'm not duplicating the newVar in my query string. Thanks! -- Matt Grimm ----- Original Message ----- From: "CPT John W.
