I have a PHP/javascript app that queries and returns info using an ajax request. On every server I've used so far, this works as expected, passing an Ajax GET request to the server and returning json data.

On a new install, the query fails and returns nothing-- I inspected the request and it turns out that rather than passing the query as a GET, the server is passing it as an OPTIONS request. Is there any reason for this? I have no idea why this might happen.

THanks!
