Session control issue

I am experiencing a problem of trying to run several variants of the same code and keep the sessions separate. Here is the scenario. I am launching all of this from a CMS. So, the CMS displays a page that has 3 links on it. Link 1 is version A of an application, Link 2 version B, etc. The three links are all the same application but different builds, in essence. They all have the same session control code. They each launch a new window, but the session variables are staying in the pool for each link, which is not acceptable. When I call Link1 and then I call Link2, they need to have an independent pool (session). I have tried to unregister, destroy, unset, to no avail. Is there a way, or am I out of luck? Hard coding is not an option, as the code has to be standard across all platforms and releases. -- Gaylen gfraley5@earthlink.net http://www.gaylenandmargie.com PHP KISGB v2.1 Guestbook http://www.gaylenandmargie.com/phpwebsite
