Cross-site HTTP requests
Cross-site HTTP requests are HTTP requests at URL addresses other than the domain of the resource making the request. The CORS specification allows the server side (that returns the resource we try to retrieve using the XHR object) to serve the resource to requests coming from resources that were served from other domains. According to the CORS specification the server side […]

We cannot initiate this HTTP request to servers other than the one from which the web page (in which the code in JavaScript that uses the XHR object is running) arrived. The JSONP technique allows us […]
