Whereas In Asp.Net, the session is process independent . That is, Asp.Net session can be independent of the hosting environment thus Asp.Net session can maintained even if IIS reboots.
In Asp, the session is cookie dependent . That is, Asp session only function when browser supports cookies. While Asp.Net supports cookieless session, so the session in Asp.Net is cookie independent .
