jQuery ajax request and 302 status code

[Ankit Garg]

Howdy,

I'm making an ajax request using jQuery and if the user's session has expired the response that I get is a 302 moved. jQuery in that case is making another request to the new path which is the login page. I want to show the user a message if the status is 302 but I'm not able to achieve this. This is the code I'm using

jQuery.ajax({ url :'checkData.ajax', complete: function(response) { if(response.status == 302) { window.alert('You have been logged out of the System'); goToLogout(); } else if(response.status == 200) { var jsonData = Ext.decode(response.responseText); var resultMessage = jsonData.available; if(resultMessage != null && resultMessage != undefined && resultMessage.length > 0) { alert("Message:"+resultMessage); } else { callback(); } } else { alert("There was some error, please try again in some time."); } } });
This is not working though, jQuery is still making another request if the user is logged out. I also tried this but got the same result
statusCode: { 302: function() { window.alert('You have been logged out of the System'); goToLogout(); } },success :function(result) { //var jsonData = Ext.decode(result); var resultMessage = result.available; if(resultMessage != null && resultMessage != undefined && resultMessage.length > 0) { alert("Message:"+resultMessage); } else { callback(); } }, failure : function() { alert("There was some error, please try again in some time."); }
Any help would be appreciated...

I am not completely sure, but I think that it's the browser's Ajax implementation that is handling the redirect. if this is the case, jQuery has no power to make it act otherwise.

I'd try making the Ajax request without jQuery's help and see if the redirect is still handled the same way. If so, then there may not be much you can do about it.

If it does turn out to be jQuery that's handling the redirect on your behalf (cool feature if so), we can explore if there's a way to have it suspend such handling.

Hi Bear,

You were right, jQuery has nothing to do with this. The browser is handling the redirect. Thanks for the help!!
