TL;DR
Tracing HTTP/1.1 pipelines, HTTP/2 multiplexing, HTTP/3 QUIC streams, and TLS handshake security layers.
Concept Overview
HTTP (HyperText Transfer Protocol) and HTTPS (HTTP Secure) are the protocols that power the web. They define how messages are formatted and transmitted between clients and servers.
HTTPS adds a security layer using SSL/TLS encryption to protect data in transit, making it essential for modern web applications.
Key Architectural Pillars
HTTP Methods
GET (retrieve), POST (create), PUT (update), DELETE (remove), PATCH (partial update), HEAD (metadata only), OPTIONS (supported methods).
Status Codes
2xx (success), 3xx (redirection), 4xx (client error), 5xx (server error). Common ones: 200 OK, 404 Not Found, 500 Internal Server Error.
Headers
Metadata sent with requests/responses: Content-Type, Authorization, Cache-Control, Cookies, User-Agent, etc.
SSL/TLS
Cryptographic protocols that provide secure communication over networks through encryption and authentication.
