RE: [PHP] Environment Variables -- HTTP_REFERER

A database solution will put too much of a burden on my database (even if I delete older records), and will slow down the scripts a little. Is there a javascript solution, with the history record of the pages visited, that I could use with PHP? If so, how would I implement that and make both languages work together to achieve this goal? Thanks for your earlier suggestion Peter. I will have to at least give your solution a try to see if it will hurt the execution speed of the scripts or not. -Darwin > -----Original Message----- > From: Thoenen, Peter Mr. EPS > [mailto:Peter.Thoenen@bondsteel2.areur.army.mil] > Sent: Wednesday, October 23, 2002 11:48 PM > To: 'Darwin'; php-general@lists.php.net > Subject: RE: [PHP] Environment Variables -- HTTP_REFERER > > > Well an ad hoc method is to immediately start a session when the > user visits > a page and then insert the following into a db the following. > > 1.
