Cross Origin Resource Sharing


Cross Origin Resource Sharing (CORS) is a mechanism to enable client-side cross-origin requests.

Specifications that enable an API to make cross-origin requests to resources can use the algorithms defined by this specification.

If such an API is used on http://example.org resources, a resource on http://hello-world.example can opt in using the Cross Origin Resource Sharing mechanism described by the specification (e.g., specifying Access-Control-Allow-Origin: http://example.org as response header), which would allow that resource to be fetched cross-origin from http://example.org.
