[thelist] Session Variables in ColdFusion

[Raymond Camden]

Hah, you wish. :> Sorry, but there isn't a way to check all sessions unless
you code around it. I can say that this is a feature many people have asked
for, so we may see it in later versions of CF.

As it stands, the hack to make it work is _very_ easy.

On logon, simply add a key to a structure in the application scope. Call it,
AllSessions. The key should be a unique identifier for the user, so just use
Session.URLToken.

For the value, use whatever you want. If you want to know all the users
online, save the username. If you want access to all the userdata, just use
Duplicate to copy it over. (But beware the Duplicate bug.)

Now, here is one problem. When the session dies, the application var will
still have a pointer. To take care of this, use onRequestEnd.cfm to save the
current time in AllSessions[Session.URLToken].LastHit. In your script that
displays all the users, check LastHIt, and if the DateDiff is more then your
session timeout, either ignore the key or delete it.

If you search the Developer's Exchange, you will find a custom tag called
SessionMagic that abstracts a lot of this for you.
