Flash & PHP Session Variable

Hi,

I am pulling my hair out over this, so any help would be greatly appreciated.

I have an upload application written in PHP and Flash. The PHP page gets the file reference information from the Flash 8 swf via $_POST. Moreover, the user never actually visits the PHP page, rather Flash uses sendAndLoad to communicate with the PHP page, all in the background. Right now, the php page cannot access the $_SESSION variables. Is there any way that I can conitnue the PHP session when doing this or does the user have to visit the PHP page?

Thanks in advance.

Steve
