cross-domain AJAX post call

I've to make a POST call(with parameter) to an asp form which is located on another server.

For develop开发者_Python百科ment, I did this on the same server, and it works perfectly, but now I'm testing it on another server, and instead of receiving a 200 status, I receive a 0 status.

I think it's because it's a cross-domain AJAX call, it's the only thing which changed. So how can I make this call? Is there any file I can put on the server/client to allow this call(like flash, ...)?

Thank you!

Yes, assuming you can change the server you connect to

You can implement Cross Origin Resource Sharing (CORS)

You need the server to return Access-Control-Allow-Origin: * if you want to allow all domains to access, otherwise return Access-Control-Allow-Origin: http://yourdomain.com

If you cannot change the server you are accessing, you need to use a proxy on the server your script comes from - alternatively investigate if they have published an API to return for example JSONP

• MDN HTTP access control (how)
• W3Org (Implemation details)
• MSDN XDR

and several links to the right of this questions

You can either create a proxy script, or use jsonp. The easier course would be to use a proxy script on your server.
