What it means in plain language
HTTP is a communication protocol used to transfer data between a browser and a web server.
Where it genuinely helps
HTTP defines request and response exchange between clients and servers, including methods, status codes, headers and caching rules.
What to decide before acting
Design correct methods and response codes and separate user errors from server failures so integrations react predictably.
How to tell whether it works
Track statuses, latency, redirects, cache headers and request identifiers rather than diagnosing only the final screen.
