What is CORS policy in web api?

Question

Accepted Answer

CORS policy allows or restricts cross-origin requests in web APIs.

CORS stands for Cross-Origin Resource Sharing.
It is a security feature implemented by browsers to prevent unauthorized access to resources on a different origin.
CORS policy is enforced by the browser based on the response headers sent by the server.
Access-Control-Allow-Origin header specifies which origins are allowed to access the resource.
If the request origin does not match the allowed origins, the browser will block the request.
CORS can be configured on the server side to allow specific origins or all origins (*).
