HELP: how can i start a new session

[ton]

I'm using a customserver control. My webpage starts with a logon form. In my
customcontrol I save the logonname, baserecordid. These values are very
important. The problem is that when a different user start the webapp, the
values are overwritten.
- Why does the customcontrol does not start a new session.?
- Or how can I save values for every user ?

BTW: I use this code:
Dim session As SessionState.HttpSessionState =
System.Web.HttpContext.Current.Session

In my custom server contro I use:

session("Connect")="databasename, server name"

and Session(üser")="jansen"

but these values are overwritten by the last user, the value of sessionid is
for every user the same. (We 're talking about internet-user from anywhere)

Please give me a hint how i can solve this
