This article traces the evolution from HTTP/1.1 to HTTP/3, explains QUIC's design and its advantages over TCP, and examines how features like connection migration, head‑of‑line blocking elimination, congestion control, and flow control improve latency and reliability for modern web applications.
Taobao migrated its long‑chain network from a private SlightSSL over HTTP/2 to a full HTTP3/QUIC stack built on the XQUIC library, adding unified TNET interfaces, UDP probing and fallback, which cut recommendation latency by up to 33 %, transaction latency 32 %, boosted upload speed 21 % and short‑video download 18 % while solving UDP port, load‑balancing and kernel memory challenges.
cURL 8.1.2, the second patch of the 8.1.x series, introduces a range of bug fixes including corrected configure handling of $CC, improved nghttp2 linking without pkg-config, HTTP/2 and HTTP/3 EOF handling enhancements, libcurl.m4 cleanup, and libssh authentication fixes.
The article surveys the evolution of web communication from HTTP/1.x through HTTPS, HTTP/2, and HTTP/3, explaining request/response structure, methods, status codes, URIs, connection handling, cookies, caching, TLS encryption, and the performance‑boosting features of header compression, multiplexing, and QUIC‑based transport.
This article provides a comprehensive overview of the HTTP protocol, covering its fundamental concepts, request methods, status codes, common headers, caching mechanisms, security differences with HTTPS, and the evolution of the protocol through HTTP/1.1, HTTP/2, and HTTP/3.
Tencent’s sTGW team introduced the TQUIC protocol stack, a lightweight QUIC/HTTP‑3 implementation with 0‑RTT handshakes, connection migration, and real‑time frames, cutting user login latency by 30 % and raising 500 ms download success from 60 % to 90 % in weak‑network conditions while shrinking the Android library to roughly 3 MB.
Tencent’s sTGW team built the TQUIC protocol stack, leveraging QUIC/HTTP3 to cut login latency by 30% and achieve 90% request success within 500 ms on weak networks, and the article details its architecture, core advantages, implementation challenges, and real‑world performance gains across multiple services.
The PHPConChina 2020 conference highlighted the challenges of TCP/IP, introduced QUIC and HTTP/3 as solutions for faster, more secure web communication, explored PHP's role in micro‑service architectures with ServiceMesh, and presented Swow's innovative features that empower PHP developers to build high‑performance network applications.
