Very often it is better to check for $HTTP_REFERER before you start using it, because as your script will be becoming bigger and many thing are depending from the refering URL - you are in trouble: strange things WILL happen! you'd better then use something like this: <PRE> <? if ($HTTP_REFERER) $myRef =$HTTP_REFERER; //or you could use something like this instead: if (IsSet($HTTP_REFERER)) $myRef =$HTTP_REFERER; ?> </PRE> ..and it is valid also for smaller scripts -- it's is safer, and plus you can add an ELSE condition to it...
