Question 1

Why should I learn HTTP status codes?

Accepted Answer

HTTP status codes are the language of web communication. Understanding them is critical for debugging APIs, diagnosing server issues, configuring proper error handling, and building robust web applications. Security professionals also need to recognize codes like 401 (Unauthorized), 403 (Forbidden), and 429 (Too Many Requests) when analyzing logs and testing for vulnerabilities like broken access control.

Question 2

What are the main HTTP status code categories?

Accepted Answer

HTTP status codes are grouped into five categories: 1xx (Informational) for interim responses, 2xx (Success) indicating the request was received and processed correctly, 3xx (Redirection) telling the client to look elsewhere, 4xx (Client Error) meaning the request was malformed or unauthorized, and 5xx (Server Error) indicating something went wrong on the server side. Each category contains specific codes with distinct meanings.
