And where did i say that the AJAX call should be *before* the session
times out?
And even if it is implemented this way - why should it not be possible
to implement a server side script which responds to the AJAX calls and
checks the existing session without resetting the session timeout?
Hint: It is also possible to implement a session handling on your own.

In this case the automatic redirect will not occur, but the session will
time out anyway.
