Question

We are using jQuery to perform ajax calling. We use different methods – $.get, $.getScript, $.post etc.

I would like perform a session check on every ajax call and once session found function should proceed to perform what is define in it’s body. Rather to perform such check by explicitly call a function in every place where ajax method is used is there better way to this?

Hypothetically, assume all jQuery ajax methods have a base method, we can use that base to perform the session check. Is such thing possible?

Thanks.

I think you can use global ajax event handler:

These methods register handlers to be called when certain events, such
as initialization or completion, take place for any AJAX request on
the page. The global events are fired on each AJAX request if the
global property in jQuery.ajaxSetup() is true, which it is by default.
Note: Global events are never fired for cross-domain script or JSONP
requests, regardless of the value of global.

I think you should use ajaxSend event:
see here: http://docs.jquery.com/Ajax_Events
ajaxSend will triggered on each ajax request, and

This global event is also triggered before the request is run
