copied!<p>I were doing similar thing on Zend/PHP project. Unfortunately, I'm not familiar with Java and there I can suggest only basic direction. </p> <p>By default, XMLHttpRequest execute redirects. So if you do a redirect during ajax request, XMLHttpRequest will execute it without letting you know that redirect happened at all. At least I found no way to catch such situation and handle it somehow. Because of that, on server side I override a redirect method. Suppose you can do something like that in Java too. Once request came from ajax (you can add a some specific header to your ajax request and check it on server) you can return a header different from <code>Location</code> header. For instance, <code>New-Location</code>, and do no actual redirect. Just stop request execution.</p> <p>On client side you can use <a href="http://api.jquery.com/jQuery.ajaxSetup/" rel="nofollow">jQuery.ajaxSetup</a> to configure global handler for all ajax requests at once. Here is how you can add a header to all requests with <code>.ajaxSetup</code>:</p> <pre><code>$.ajaxSetup({ headers: { XHTTPRequest: 'true' } }); </code></pre> <p>Additionally you can set a global <a href="http://api.jquery.com/ajaxSuccess/" rel="nofollow">ajaxSuccess</a> and <a href="http://api.jquery.com/ajaxError/" rel="nofollow">ajaxError</a> handlers. They will be executed before any success/error handler of a separate ajax request. In global ajax success you can take a header from <code>xhr</code> object passed as a third parameter to callback function and do a redirect:</p> <pre><code>var newLocation = xhr.getResponseHeader("New-Location"); if(newLocation) document.location = newLocation; </code></pre> <p>Basically, you can return special object instead of header or find some other way to pass a new location to your <code>ajaxSuccess</code> callback. </p>
