A Web Server is software (and the underlying hardware) that stores, processes, and delivers web pages to Internet clients—most commonly web browsers. It operates primarily over the HTTP (Hypertext Transfer Protocol) and HTTPS protocols to fulfill client requests across the World Wide Web.
Whether serving static HTML pages, CSS stylesheets, images, or forwarding dynamic requests to servlet containers, understanding how a web server operates is essential for every web developer.
How a Web Server Works
-
Listens on a Port: A web server binds to network ports (standard port
80for HTTP or443for HTTPS) waiting for incoming requests. -
Accepts Connection & Parses Request: When a user types a URL or clicks a link, the browser opens a TCP connection and sends an HTTP request specifying the resource path and method (e.g.,
GET /index.html). - Locates Resource: The web server searches its document root directory for the matching file or evaluates request routing rules.
-
Sends HTTP Response: If found, the server transmits an HTTP response header (such as
200 OK) along with the content payload. If not found, it returns an error status code like404 Not Found.
Popular Web Servers
- Apache HTTP Server: One of the most mature, flexible, and open-source web servers in computing history.
- Nginx: High-performance, event-driven web server often used as an HTTP cache and reverse proxy.
- Microsoft IIS: Enterprise web server integrated tightly with Windows Server environments.
