INSIGHT

HTTP Basics and HTTPS Relation

  • HTTP is a simple request-response protocol enabling browsers to communicate with servers using a path, headers, and a body.
  • HTTPS includes HTTP but adds encryption, maintaining the same request structure while securing data in transit.
ADVICE

Use HTTP Status Codes Correctly

  • Learn HTTP status codes to properly handle responses, like 200 for success and 404 for not found.
  • Use the correct status code class: 2xx success, 3xx redirects, 4xx client errors, 5xx server errors to communicate state accurately.
INSIGHT

HTTP Uses TCP, Not UDP

  • HTTP only works over TCP, which provides ordered, reliable byte streams.
  • UDP does not support ordered or guaranteed delivery, making it unsuitable for traditional HTTP protocols.
