This article walks through every step that occurs when you type a URL— from the browser’s DNS lookup and HTTP request, through server processing, redirects, HTML rendering, and subsequent resource and AJAX calls—revealing how browsers, servers, and CDNs cooperate to deliver a web page.
This guide explains how configuring the Nginx expires directive for CSS files can prevent redundant network requests by letting browsers rely on local cache for a specified period, improving page load performance.
This guide explains how to configure Nginx's global parameters, event settings, and HTTP block—including worker processes, error logs, connection limits, upstream load balancing, virtual hosts, and location directives—for optimal backend performance.
This article presents practical guidelines for designing, versioning, securing, and documenting RESTful APIs, covering resource modeling, URL conventions, filtering, sorting, pagination, authentication, rate limiting, error handling, and response formats to help developers build flexible and user‑friendly public APIs.
This article provides a structured, high‑level introduction to the HTTP protocol, covering its history, versions, network layer placement, request and response formats, headers, status codes, media types, and state‑keeping mechanisms such as cookies and query strings.
The article explains the origin of RESTful architecture, defines its key concepts of resources, representations, and state transfer, outlines how HTTP verbs map to operations, and highlights typical design mistakes such as verb‑laden URIs and versioning in the URI path.
This article explains how to achieve ultra‑high HTTP request rates by using load‑generating tools such as Apache Bench, httperf, JMeter and Tsung, discusses Linux socket limits, provides step‑by‑step installation and configuration examples for Tsung on CentOS, and shows how to run tests and interpret the results for building a high‑performance web cluster.
This tutorial walks you through setting up a PXE‑based automated Linux installation environment, covering DHCP, TFTP, HTTP services, kickstart configuration, necessary boot files, and the final deployment of CentOS 6.5 on virtual machines.
This guide explains how to create an Nginx configuration file that denies access from unwanted user agents, empty agents, and non‑GET/HEAD/POST requests, shows how to include the file in the server block, reload Nginx, and test the rules with curl.
This article reviews several Erlang-based web servers and frameworks—including Yaws, Mochiweb, Misultin, Cowboy, httpd, SimpleBridge, webmachine, Nitrogen, Zotonic, and Chicago Boss—highlighting their features, documentation quality, integration with supervision trees, and suitability for building high‑performance HTTP services.
This article explains the fundamentals of web servers, application servers, and web containers, describes the Java Servlet API—including Servlet, ServletContext, ServletRequest, ServletResponse, and session handling—and provides guidance on thread safety with illustrative code examples.
This article presents a comprehensive, seven‑step methodology for designing, implementing, and maintaining Web APIs—covering business use‑case definition, semantic description, state‑diagram modeling, naming harmonization, media‑type selection, semantic archive creation, coding, and publishing—while offering interviews and further reading recommendations.
