You should probably subclass Iliad.Session, then use it in the
SessionManager: Iliad.SessionManager sessionClass: MySession


Then in your session subclass, you can add your code in the #expire

Unfortunately, there is currently no easy way to do that if your image
isn't in the Public directory. You can have a look at
Core/RequestHandlers/FileHandler.st, but I'll try to provide a better
answer soon.
