I'm configuring the applet, trough the "cookiename" and "cookievalues" params, to include a cookie that preserves the PHP session. Everything works fine for the first uploaded file, however, on the second request the applet sends two "Cookie" headers, because the server sent a cookie back in the first HTTP response:

1st request: 1st response: 2nd request: 2nd response: -> PHPSESSID missing

If the applet is trying to send back the received cookies, it should at least join the data under a single "Cookie" header. Although the 2109 RFC doesn't seems to limit the use of this header, I can certainly tell from practice that Apache ignores the first header in favor of the second.

Could you try to pass PHPSESSION in URL instead ?

That would be the partial solution that I'm using now. The problem is, some of the servers that I tried to deploy JFileUpload on, have PHP configured with "session.use_only_cookies" to "On", to increase the security.
Also, a couple of servers require a special cookie (usually named something like "X-Mapping-caklakng") to keep the session between multiple servers in a load balancing system.
Improving the cookie support will increase the number of supported server configurations.
