Cross-origin resource sharing (CORS) allows web pages in one domain to access restricted resources from your domain. Specify external origin hostnames, methods, and headers that you want to accept via HTTP response headers. Full support of CORS requires allowing requests that use the OPTIONS method. See allow_options.
