Why don't synchronous ajax calls in jquery support timeout?

Question

I was reading here that synchronous ajax calls in jquery don\'t time out.

Is this a technical limitation, or just something the authors didn\'t feel like supporting

Answer 1

A synchronous AJAX call blocks until the request has been finished. Implementing a timeout is not possible for technical reasons, because the AJAX call would have to be executed later.

If an AJAX call is executed later, the function somehow has to implement a blocking feature, to stop the code from running further after the AJAX call, and execute it again after a timeout - not possible.
