How can I callback AJAX success function after successful Spring Security login?

Question

I have clients that issue AJAX calls. These calls reference URLs that are protected by Spring Security on the sever side. If the user's session has timed out, I have a login form popup in a lightbox. After the user has successfully logged in, I would like the client to re-execute AJAX call.

Here's an example of the client side code that makes an AJAX call:

function handleSearchClick(evt) {
    var setupOptions = { 
        success: loadSearch,
        type: "POST",
        dataType: "json",            
        url:   "../search.ajax",
        error: handleError, // how can I pass callback info i.e. I want to be able to execute $("#searchForm").ajaxSubmit(setupOptions); from handleError? 
        timeout: 50000
    };                
    $("#searchForm").ajaxSubmit(setupOptions);
}

When the authentication fails, the server returns a 401 which results in the client calling handleError. Is it possible to pass a callback function to handleError? I would want the callback to re-execute

$("#searchForm").ajaxSubmit(setupOptions);

I have seen solutions to this problem where the server returns a success response on AJAX calls that have a session timed out. Then, the success function looks for something in the response to know the session timeout. The client then stores a callback function there. I prefer though to handle this in the error function.

Answer 1

The request executed by

$("#searchForm").ajaxSubmit(setupOptions);

can be re-executed in the handleError function by calling

$.ajax(this);

There is no need to pass in a callback function to re-execute:

$("#searchForm").ajaxSubmit(setupOptions);
