I’ve implemented a log in session “thing” that essentially works by
holding the model of the logged in user in a session variable, like
session[:user] = user
However let’s say at this point in time, should an administrator of the
system decide to revoke this user’s account, the session variable for
that currently logged in user is still valid, and hence he will still be
able to access the system!
Is it possible to modify a session variable even if it doesn’t belong to
the currently running process? The only other alternative for such a
problem would be to poll the user database table each time to check if
that user is still valid, which doesn’t sound all that great.
