Which mechanism allows a web application to request resources from a different origin than its own?

Accepted Answer

Cross-Origin Resource Sharing (CORS) is the standard browser security mechanism that allows servers to specify which origins are permitted to access their resources. JSONP is an outdated workaround, CSRF is a security vulnerability, and HSTS is a policy for enforcing HTTPS connections.
