I have a script that after customers have made payment into my paypal account they return to my site and the session variables that I have created will write their details to a MySQL database. For some reason which I can not find out is that this doesn't happen but when I test the code by passing the paypal payment everything works fine. So the question is does the paypal site after payment is made kill all sessions on their server and does this affect the sessions created on another server.

Thank a lot for that information, I tested this by typing into my form and create the sessions then I left the page to go to another website, I then returned to another page which uses these sessions in the page to add to my database and the sessions are still there and inserting into the database without any problems. Will be testing the whole thing again with a paypal payment.

"I expect to pass through this world but once. Any good therefore that I can
do, or any kindness or abilities that I can show to any fellow creature,
Lord, let me do it now. Lord, let me not defer it or neglect it, for I shall
not pass this way again."
