Solution 1:

You can't make AJAX requests cross-domain, unless it returns a Access-Control-Allow-Origin header. Cross-site HTTP requests initiated from within scripts have been subject to well-known restrictions, for well-understood security reasons. For example HTTP Requests made using the XMLHttpRequest object were subject to the same-origin policy. In particular, this meant that a web application using XMLHttpRequest could only make HTTP requests to the domain it was loaded from, and not to other domains.
