Pass request headers in a jQuery AJAX GET call

As of jQuery 1.5, there is a headers hash you can pass in as follows:

$.ajax({    url: "/test",    headers: {"X-Test-Header": "test-value"}});

From http://api.jquery.com/jQuery.ajax:

headers (added 1.5): A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.

Use beforeSend:

$.ajax({         url: "http://localhost/PlatformPortal/Buyers/Account/SignIn",         data: { signature: authHeader },         type: "GET",         beforeSend: function(xhr){xhr.setRequestHeader('X-Test-Header', 'test-value');},         success: function() { alert('Success!' + authHeader); }      });
