HTTP Status Code Reference

Outstanding features

Why is it important to understand HTTP Status Codes?

HTTP Status Codes are the communication language between client and server. Each response from the server is accompanied by a status code indicating the result of the request. Understanding status codes correctly helps you: (1) Debug API faster - immediately know if the error is in the client or server; (2) Handle errors properly in code - distinguish between 401 (login required) vs 403 (no permission); (3) SEO optimization - 301 vs 302 redirects affect SEO differently; (4) System monitor - spike 5xx errors signals a server problem. This is the fundamental knowledge that every web developer needs to master.
