Using JSF 2.0 / Facelets, is there a way to attach a global listener to all AJAX calls?

Question

Is there a way to attach a global listener to all AJAX calls in JSF? Maybe through a phase listener or something?

Here is the conundrum... Lets say you\'re using f:a

Answer 1

To redirect a jsf ajax request you need xml as follows

Here XXX is url you want redirect to happen.

On ajax call redirect sent is not as above hence no redirect.

To get the desired result have a filter for all jsf request except few pages(login page) and check session is valid and if it is really jsf ajax call by checking header "Faces-Request", its value should be "partial/ajax". If session has expired and is ajax request send above xml as response.

It should work.
