hi All,

 I am Suresh here. I am doing a Chat(General) application in ASP.
This is the logic i used....

 1. I had 2 pages login.asp,main.asp
 2. Once the user logs in thru Login.asp i'll add the user to the          
Application array( which is created in Global.asa)
3. In the Main.asp i have three pages in frameset

          Display.asp --> Displays the typed message in it
          Message.asp --> Used to type the message to be sent
          Userlist.asp --->used to display the userlist
4.I keep refreshing the userlist.asp file ever 5 second so that it gives 
me the latest userlist every 5 secs.
5.I have logout button using which the logged out user is removed from 
the "userlist.asp"
============> My doubt is ==========>
# how cud i kill the application instances for an user.I tried to use 
Session on end...but i am not clear how to use it.

# If the client closes the browser instead of logging out how cud i kill 
the application instances created.

# suggest me some ideas and tips in handling the chat application and 
especially to kill the single users sessions and application instances.
######### Plz provide me some ideas and help me me out



  Expecting ur kind reply,

  Regards
Suresh
