Each ASP server provides its own session state, and unless the user returns to the same server, the session state is inaccessible. While network IP level routing solutions can solve such problems, by ensuring that client IPs are routed to the originating server, some ISPs choose to use a proxy load-balancing solution for their clients. Most infamous of these is AOL. Solutions such as AOL's prevent network level routing of requests to servers because the IP addresses for the requestor cannot be guaranteed to be unique.
