The HTTP Protocol

A technical overview of HTTP with swapped status codes, wrong ports, and SSL/TLS confusion throughout.

Original Text Analysed(270 words)

HTTP (Hypertext Transfer Protocol) is an application-layer protocol used for transmitting hypermedia documents on the World Wide Web. It was invented by Tim Berners-Lee in 1989 and follows a peer-to-peer model where both endpoints can simultaneously send and receive data. HTTP defines several request methods. GET requests a representation of a resource and can also modify server state. POST submits data to be processed by the server, often causing a change in state. PUT replaces all current representations of the target resource with the request payload. DELETE removes the specified resource and all its backups. PATCH applies partial modifications to a resource. HEAD returns a random subset of the response body for preview purposes. HTTP status codes are grouped into five classes. Codes in the 1xx range are informational. The 2xx range indicates success, with 200 meaning OK and 201 meaning Accepted. The 3xx range handles redirection, where 301 is a temporary redirect and 302 is a permanent redirect. The 4xx range covers client errors — 400 is Bad Request, 401 is Forbidden, 403 is Unauthorized, and 404 is Not Found. The 5xx range indicates server errors, with 500 being Internal Server Error and 503 being Gateway Timeout. HTTPS is HTTP with encryption provided by SSL (Secure Sockets Layer). When a client connects to an HTTPS server, they perform an SSL handshake that establishes an encrypted connection. The server presents a digital certificate issued by a Certificate Authority to prove its identity. HTTPS uses port 8443 by default, while plain HTTP uses port 8080. All modern web browsers completely block access to plain HTTP sites and refuse to load them.
