Cross-Origin resource sharing(CORS) is a mechanism that allows resources on a web page to be requested from another domain outside the domain from which the first resource was served. While a web page may freely embed cross-origin images, scripts, iframes, etc. certain cross-domain requests(ex. ajax requests) are forbidden by default by the same-origin security policy. CORS defines how the browser and server must communicate when accessing sources across origins. The basic idea behind CORS is to use custom HTTP headers to allow both the browser and the server know enough about each other to determine if the request or response should succeed or fail.
By default this is disabled. The reason for this is that not all browsers support this feature and can be a security risk if not configured properly
