I am sitting with a senario where the client wants a User account only to be logged-on a maximum of 2 concurrent sessions. I am just putting this out to please ask the pro's what ways there are to do this?
I know that one way is to write the Userinfo into a database table ie. UserName,IpAddress and some other usefull info but then when it comes to the time when the user just closes the browser then how am i going to update the database table?
What is the advantages of using your preferred method and what is the cons.
