I think I may have found the problem. My webserver (I rent space on a commercial webserver) does a strange thing with regards to URL's: when I type in "www.addr.com/~mgardne/somepage.html" the browser actually gets redirected to "www22.addr.com/~mgardne/somepage.html" the www gets changed to www22. I think the servlet container was looking at some of my URL's and getting confused as to what was coming from where or something. Anyway, I hard coded some of my url's to absolute urls's with the http://www22.addr.com in them, and my sessions work now. not a pretty fix I know, but atleast I have it working.
