CORS
Cross-Origin Resource Sharing (CORS) is a tool that uses HTTP headers to help servers determine which requests from other resources can access the current, cross-origin resource.
In most cases, browsers will make a “preflight” request to the host server to ensure the actual request will work. This is another function of CORS.
CORS
- Access-Control-Allow-Origin
- Determines which requests from other pieces of web content have access to the current resource.
