Exclent point, Here is what I need to do, I have a web application which allows users to interact with a flash object on a web page. Now for the problem the flash object writes an XML file to the server (I didn't make the flash object so I don't have control of this object), so I need to make sure that only one person has access to the object at any given moment. My first thought was to use sessions, but that won't work across users, so then I thought of just making a lock file and killing the lokc file when a session dies. But I am not all that thrilled at changing the behavior of sessions across the entire website for this one applicaton. Any thoughts on maintaining user control?

Then maybe I can give you some ideas. to answer what you've said so far: Mixing a class into session during the context __init__ will override the session for the entire appserver. One way to use session classes on a context-by-context basis is to override the Page.session() method with something that wraps the session in another class. That won't help with the expiration issue directly, but you can use that in combination with a MixIn to achieve what you need. For example, you can MixIn a class which overrides Session.expiring() and performs certain logic depending on what type of session object it is. This type would be determined by an attribute of the MixIn class. Then in the Page.session() method, you can set this new type attribute to identify the Session. When the expiring functions runs, the appropriate logic will execute. Really though, what "file housekeeping" do you need to do at expiration time? The best scenario is to rearchitect your use of session objects to eliminate the need for such housekeeping.

Can someone please tell me how I can access a session variable via a task? What I need to do is to do some file house keeping once a session expires. I thought I could do this by using MixIn and simply over riding the expiring method within a context, but it seems the this over rides the method for the all contexts (not really what I had in mind). So now the only thing I can think of is to use Tasks, but I am at a loss as to how to proceed. Any and all help would be much appreciated Thanks Jose ------------------------------------------------------- This SF.net email is sponsored by: ObjectStore.
