Hey...maybe you've solved this one by now but in case you havn't, I think the problem is the PHPSESSID param the swfupload appends to the upload URL you supply.
If you switch on the swfupload debug, you can see this clearly.
Not sure how to solve this though...the swfupload uses the PHPSESSID in 'post_params' so I would have expected it to be a POST, rather than GET param.
If you have solved this...any help greatly appreciated.
I'm fairly new to php but have used the swfupload-er successfully in java - it rocks!
