cross-domain AJAX post call

Question

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

For development, I did this on the same server, and it works perfectly, but

Answer 1

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

• W3Org (Implemation details)

Answer 2

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