HTTP/3 (RFC 9114)

The HTTP semantics mapping over QUIC, delivering lower-latency multiplexed transport.

by IETF

Content Security Policy (CSP)

A W3C security standard delivered via an HTTP header that controls which sources a browser may load, mitigating cross-site scripting and data injection attacks.

Webhook

A server pushes event notifications to a client-registered HTTP endpoint as events occur, replacing inefficient polling with real-time callbacks.

What is CORS and why do I get CORS errors?

Cross-Origin Resource Sharing (CORS) is a browser security mechanism that controls whether a web page can make requests to a different origin (scheme, host, or port) than the one that served it. Browsers block such cross-origin requests by default unless the responding server returns headers like `Access-Control-Allow-Origin` that explicitly permit them. CORS errors mean the server did not return the required headers, not that the request itself failed on the server. The fix is to configure the API to allow the calling origin, methods, and headers; for credentialed requests the server must echo a specific origin rather than a wildcard.

What is the difference between HTTP/2 and HTTP/3?

HTTP/2 introduced multiplexing of multiple requests over a single TCP connection, header compression, and server push, reducing latency compared with HTTP/1.1. However, because it runs over TCP, packet loss on one stream stalls all streams, a problem called head-of-line blocking. HTTP/3 solves this by running over QUIC, a transport built on UDP, where streams are independent so loss affects only the affected stream, and it integrates TLS 1.3 for faster connection setup. HTTP/3 also resumes connections more smoothly across network changes, benefiting mobile clients.

Core Web Vitals

Google's set of user-centric web performance metrics, LCP, INP, and CLS, that quantify loading, interactivity, and visual stability of real page loads.

Lighthouse Performance

Google's open-source web auditing tool that runs synthetic page loads and produces a 0-100 performance score from lab metrics like LCP, TBT, and CLS.

HTTP/3 and QUIC Protocol Benchmark

Measures how the QUIC-based HTTP/3 transport compares to HTTP/2 over TCP on connection setup, throughput, and latency, especially on lossy networks.
