I am using swf-upload to handle file uploads on a site I am working on.
The problem is the catching function, called swf-upload.php. If I visit the URL it is at directly it works fine, it correctly reads starts the session and gets the user rights, but when the web page calls it with the ajax callback it claims the session is empty.
I am using a combination of error handlers and output logging to find out what it's doing and there is utterly no difference in the code path between the direct access and the ajax access.
Any ideas what's up?
