Php sessions and flash

I'm having a problem with using cookies and flash. When I pointed that the problem was _with_ cookie and flash, is when I resolv the same program using a pure HTML interface. The exact problem, is that the session number, keep on changing when working with the flash interfase. This flash interfase, is not realising that it already has a session, a cookie, and a couple of varibles; and keep on creating again them every time it returns to the php code. Using a short example, lets say that I have a Flash that calls a php that executes a "print $session" when the user clicks on a flash button. Every time that the user clicks on the flash, the session variable keeps on changing. What I would like to know, if is some has had a similar problem, or point me in some direction where I can get some more information about working with cookie & flash. -- Rodrigo Castro Universidad Latina de CR
