Ajax cross server issue with "Ajax Upload" script

[schilly]

Hey,

 

I'm running into some weird issues doing cross server ajax calls with http://valums.com/ajax-upload/. The request works fine and the file uploads and saves properly but for some reason the xhr response is invalid so I get an error every time even though the json success message is returned.

 

PHP Request Processor:

<?php

//check for cross server access check
if($_SERVER['REQUEST_METHOD'] == 'OPTIONS' && $_SERVER['HTTP_ORIGIN'] == 'http://domain1'){
header('Access-Control-Allow-Origin: http://domain1');  
header('Access-Control-Allow-Methods: POST, GET');  
header('Access-Control-Allow-Headers: X-Requested-With,X-File-Name');  
header('Access-Control-Allow-Credentials: true');  
header('Access-Control-Max-Age: 1728000');  
header("Content-Length: 0");  
header("Content-Type: text/plain");  
exit();

} else {
//return success message
echo htmlspecialchars(json_encode(array('success'=>true)), ENT_NOQUOTES);
exit();

}

?>

Yet when I look at the xhr response, the readyState is 4 meaning it's done but the status is 0 and there is no responseText. Anyone have any ideas what I can try? The response works fine if I do it on the same server.

 

I'm guessing it has something to do with the headers but I'm really not sure. It seems like everything other than the xhr readyState is null.

 

Anyone have anything I could try?

 

Thanks.
