The fundamental communication protocol for web applications in the request–response model. A browser or API client sends a method, URL, headers, and data, and the server returns a status code and response.
Why it matters
It's the common language of the internet: every website, API, and integration communicates via HTTP requests and responses. Understanding methods and status codes reveals what's actually happening between systems.
What's missing without it
Without understanding HTTP, diagnosing integrations becomes guesswork — and the difference between errors 401, 404, and 500 points to entirely different root causes.
When it is used
In any network-related work: integrations, APIs, error diagnostics, website performance.
How we use it
A frontend CMS sends an HTTP request to the backend to fetch a list of articles.
