This article explains the fundamentals of HTTP and HTTPS, comparing their features, security mechanisms, ports, and performance, and details how internet messages travel through DNS, routers, IP and MAC addresses, as well as the roles, characteristics, and differences of cookies and sessions.
This article explains the HTTP QUERY method—a safe, idempotent request type that carries query payloads in the body, contrasts it with GET and POST, details caching behavior, the Accept-Query header, and provides practical examples of direct and indirect responses.
This article explains the fundamentals of HTTP, how browsers build and send requests, the structure of request and response messages, and the performance improvements introduced by HTTP 2.0 and the QUIC protocol built on UDP.
This article explains the fundamentals of HTTP and HTTPS, covering the protocol structure, common request methods, request and response message formats, differences between GET and POST, response status code categories, a full HTTP transaction flow, and the encryption mechanisms and drawbacks of HTTPS.
This article explains the fundamentals of HTTP and HTTPS, covering request and response structures, common methods, differences between GET and POST, response codes, the complete request flow, and how HTTPS adds SSL/TLS encryption for secure communication.
This article traces the development of the HTTP protocol from its earliest 0.9 version through 1.0, 1.1, 2.0, and the modern HTTP/3 over QUIC, detailing key features, header compression, multiplexing, caching mechanisms, server push, and the security and performance trade‑offs of each iteration.
The article explains how HTTP/3, standardized as RFC 9114 after five years of work, replaces TCP with the UDP‑based QUIC protocol to overcome HTTP/1.1 and HTTP/2 limitations such as head‑of‑line blocking, improving multiplexing, congestion control, and security.
This article traces the evolution of HTTP from its early TCP‑based origins through HTTP/1.0, 1.1, SPDY, HTTP/2, and finally to HTTP/3, explaining how QUIC over UDP addresses latency, head‑of‑line blocking, and security challenges of previous versions.
This article reviews Google’s pioneering SPDY protocol, its key features and impact on HTTP/2, then explores the disruptive QUIC protocol built on UDP, detailing its connection setup, Diffie‑Hellman encryption, multiplexing, connection migration, and other enhancements that boost web performance.
This article traces the evolution of the HTTP protocol from its early days through HTTP/1.0, 1.1, SPDY, HTTP/2, and finally to HTTP/3, explaining how QUIC over UDP addresses TCP's latency and security limitations while also highlighting remaining challenges.
This article traces the evolution of HTTP from its 1991 origins through HTTP/1.0, 1.1, HTTP/2, and finally HTTP/3, explaining how QUIC over UDP addresses TCP’s latency and security limitations while also highlighting remaining challenges.
This week’s tech roundup highlights JD’s new federated learning platform, Facebook’s AI-driven search for renewable-energy catalysts, ARM’s high‑performance AIPU, NVIDIA’s data‑center DPU, Chrome’s rollout of HTTP/3 with QUIC, Canonical’s take on Windows‑Linux migration, plus recent advances in stereo matching and mobile sensor action recognition.
This article explains the fundamentals of HTTP, the differences between GET and POST, common status codes, HTTPS and TLS handshakes, the improvements introduced by HTTP/2 such as binary framing, multiplexing and header compression, as well as the role of QUIC and DNS in the end‑to‑end web request flow.
This article provides a comprehensive overview of HTTP fundamentals, compares GET and POST, explains common status codes, details HTTPS and TLS mechanisms, introduces HTTP/2 features such as binary framing, header compression and server push, and walks through the full request‑response flow from DNS lookup to page rendering.
This article walks through the essential concepts and step‑by‑step processes of DNS resolution and HTTP communication, illustrating how a browser transforms a URL into an IP address, queries multiple name servers, and finally retrieves web content via HTTP requests.
The series teaches mobile developers how to use Chrome’s Network panel and Wireshark, explains connection keep-alive, demonstrates HTTP 1.x head-of-line blocking with Go and OkHttp, and clarifies fixed-length versus chunked body transfer, providing practical code and traffic analysis for deeper protocol understanding.
This comprehensive article explains the origins of HTTP, its relationship with the TCP/IP protocol suite, the three‑way handshake for establishing connections, the structure of HTTP request and response messages, status codes, long and short connections, and the four‑step termination process, providing essential knowledge for web development and networking interviews.
HTTP/2, the modern successor to HTTP/1.1, introduces binary framing, header compression, multiplexing, server push, and other enhancements that dramatically reduce latency and improve efficiency, making web pages load faster and more reliably across browsers and servers that support the protocol.
This article provides a comprehensive overview of HTTP, TCP, UDP, and socket communication, explaining protocol layers, request/response structures, key headers, and the differences between GET and POST methods for web development.
This article explains the HTTP protocol, outlines the purposes of GET and POST methods, details their characteristics, compares them across factors like caching, security, and data limits, and introduces additional HTTP methods such as HEAD, PUT, DELETE, OPTIONS, and CONNECT.
