Hi,
Is there a possibility to invalidate stale sessions and to delete objects linked to a
no more valid session?
My problem:
In my processing I create a file using the sessionId as filename.
If now the user does not correctly log off and instead just does nothing or closes his
browser the session will at some time become invalid (latest at closing the browser).
But the file will rest forever:
So my idea was to search at each new login all existing such (in a special directory)
files, to compare their filenames with all still valid session Ids. And if a certain
session Id is not valid anymore I would have deleted the file.
Now how can I find all valid session Ids. This was possible using the
HttpSessionContext class. But in the API description is written that this interface
will be deleted as of Servlet API 2.1.
Is there another possibility to find all valid session Ids or to check if a certain
session Id is still valid?
