Frequently Asked Questions

What do the 200 series status codes mean?

The 2xx class indicates that the client request was successfully received, understood, and accepted (e.g., 200 OK or 201 Created).

What is the difference between 401 and 403?

401 Unauthorized means the user's identity is unauthenticated. 403 Forbidden means they are authenticated, but lack the permissions to do the action.

Why do browsers show '504 Gateway Timeout'?

A 504 happens when a proxy server (like a load balancer or edge server) did not receive a timely response from the main upstream server.

Are these codes universally the same for everything?

Yes. They are formally established by IETF protocols (RFC standards) and all conforming browsers and servers adhere to them.
