Aborting AJAX requests
Consider a case where a user is allowed to select a date on a page and an AJAX request is made to the server to fetch some data against that date. If the request is under processing and in the meantime the user selects another date and a new request is sent, the server now has two requests pending.
Imagine what will happen to an application if there are multiple users repeating the same behavior. Desirable behavior in this case will be to cancel the pending request and allow only the current one.
This recipe will explain how to cancel any pending requests.
