Is there any way to use the same session for Shockware (Uploadify) with Firefox/ Chrome/ Opera?

I don't know why, but it works very randomly for me. From the DB i can see only 1 session created for Shockware, but sometimes for example if I upload huge ammount of images, something happens with Shockware session and I still see 302 error. Maybe uploadify is using text based cookie and it's caused by cookie 4kb limitation. If somebody has the same issue, please help...
