I have read a number of articles but I would like to the experts at this place to give me a second opinion.
I have two requirements on my web application(build vb.net):
1. User should be billed based on the total time he or she has been logged in (could this be solved with Session_End?,
which doesnt work with StateServer and SQL Server Sessions:-( )
2. Prevent multiple users of an ASP.NET application from using the same credentials to log in at the same time from different machines.
How could the two requirements be meet, to use session_start and session_end would maybe a easy way to meassure how long time the user is logged in but how to pevent the second requirement I have no idea about.
