For example: Access-Control-Allow-Origin: If the server decides that the request should be allowed, it sends a Access-Control-Allow-Origin header echoing back the same origin that was sent or * if it’s a public resource. An example Origin header might look like this: Origin: The Origin header contains the origin (protocol, domain name, and port) of the requesting page so that the server can easily determine whether or not it should serve a response.

The basic idea behind CORS is to use custom HTTP headers to allow both the browser and the server to know enough about each other to determine if the request or response should succeed or fail.įor a simple request, one that uses either GET or POST with no custom headers and whose body is text/plain, the request is sent with an extra header called Origin. Source: The Cross-Origin Resource Sharing methodĬross-Origin Resource Sharing (CORS) is a W3C Working Draft that defines how the browser and server must communicate when accessing sources across origins. This method is not suited for cross-domain resources as browsers like Firefox will not allow you to change the document.domain to a completely alien domain. With this method, you would be allowed to exectue javascript from an iframe sourced on a subdomain on a page sourced on the main domain. However, by the same reasoning, could not set document.domain to. For example, assume a script in the document at executes the following statement: document.domain = "" Īfter that statement executes, the page would pass the origin check with. If it does so, the shorter domain is used for subsequent origin checks. Note that this is an iframe method that sets the value of document.domain to a suffix of the current domain.
