Site Wide Session Variables

[Newsgroup_User]

Is it possible to create a session variable that can be viewed on everyone
one the site. Normally I session the user's username and site privledge, but
that can happen for multiple users at anyone time (i.e. Session.username).
Is it possible to create a session that can be used / viewed by everyone
whos on the site?

The goal is to set people to a sitewide session variable to show whos online

There's APPLICATION scope variables, which are visible to everyone on the site.

SESSION variables are only visible to that session.

You can't do it with a session variable, but you could have an application scope array containing the user names (i.e. application.username).
