CORS
Cross-origin resource sharing (CORS) is a browser standard mechanism provided by the World Wide Web Consortium (W3C). It defines the interaction methods between client-side web applications in one origin and resources in another origin. In web page requests, website scripts and contents in one origin cannot interact with those in another origin because of Same Origin Policies (SOPs). This section introduces CORS and describes how to configure CORS.
