How to determine if async request form ajax form was redirected?
In my case request is redirected to login page if user's session is closed.

I tried to check arguments of OnComplete, OnSuccess and OnBegin events (OnFailure is not called) but no one helped.

Currently I have entire Login page embaded in the div of current page in case of session closing.

The only way I see how to awoid this - is code like this:

```
function onSuccessPost(a,b,c) {
   if (a.indexOf("<!DOCTYPE html>") == 0) {
      window.location = window.location;
   }
   // ...
}

```

But this solution seems a bit ugly.

Any ideas?
