Yes! A third cookie! That would seem to be what I am asking.
Since posting, I tried using cookie_value to pass sessioncookie and cookie1_value to pass my security cookie, and that is working, but only tested to see if I could connect. I was able to connect, see the albums, and retrive picture already on the server. However, I am not sure if reassigning cookie_value from session_id() to 'sessioncookie' broke something else.
In the end, it does appear that passing a third cookie is the answer to my problem. I love using the java applet, and would like to make it available to the users of the site.
Thanks for the taking the time to respond!
