I have done multi-server installs from 2 server to a 30 server cluster. All of those used cookies, client vars, and sticky sessions. Because without them doing what you want to do is near impossible.
Your url id could work but there is no security in it. If a malicious user saw that then they could play around with the url and hijack another users session. If you are going to store the session as a packet in the DB you are restricting yourself as to what you can store in session. Storing the packet in the db is just simulating client var storage anyways. This situation sounds more like a non-tech person driving technical decisions. --Dave ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ColdFusion MX7 by AdobeĀ® Dyncamically transform webcontent into Adobe PDF with new ColdFusion MX7.
