Answer 1

This is basically a Cross-origin resource sharing (CORS) problem.

You are making an ajax request from a page of different domain. which is not allowed.

To allow it you will have to append Access-Control-Allow-Origin in the response header of the server page by adding this on the top of the server page

header('Access-Control-Allow-Origin: *');  

Note: the '*' at the end means it will accept any request from any website, for added security you could do this

header('Access-Control-Allow-Origin: http://yourwebsite.com');
