Check if a certain sessionID is yet valid ...

[Christian Sengstock]

Hi list,

i want to check if a certain sessionID is a valid sessionID in my cocoon environment or not. This should be sort of an admin task,  
    * i'm not the user having a session object, but a new user which want's to get access to this information *
I have some files which are named like some sessionIDs and i want to delete them if the session is invalid - inside of my application.

What's the best way to check for validity of a certain sessionID in cocoon ?

Thanx a lot,
chris
