You can use session within javascript too i believe. Hmm javascript setting server-side session data?? Sounds weird, but i'll look into it..
server-side session data? i never heard of server-side sessions... AFAIK they are send in the HTTP headers from and to the server. Cookies are nearly the same as sessions, i found this article (with examples) that goes about parsing cookies from javascript. So you could also do it with cookies. http://www.javascriptkit.com/javatutors/cookie2.shtml

Nice tutorial thanks for that, i'll look it up, maybe intergrate it right away, would really make my day if i could :)) Regards, Tim
It's not too hard, but if you already did a lot of work on the form processing, you prefer not to write it all over again i think ;) Tijnema
