[Seaside] How to get the number of user connected

[Florian Minjat]

Thank you all for this help. It is clear I need to do custom sessions. 
I don't know why I didn't thought of it before.

Currently I use the default behavior for session expiration. So they 
just wait to be GCed. Is there an existing 'session reaper' available 
somewhere or should I make it myself? It doesn't seems to difficult, 
but I dislike coding the wheel again.

Thanks again,
