webkiszolgálóhoz

A webkiszolgálóhoz, or web server, is a software or hardware system that processes requests made from web clients, most commonly web browsers. When a user types a web address into their browser, the browser sends a request to a web server. The web server then finds the requested file or resource and sends it back to the browser, which displays it to the user. This fundamental interaction forms the basis of how the World Wide Web functions.

Web servers are responsible for storing, processing, and delivering web pages to users. They can be dedicated physical machines or virtual instances running on more powerful hardware. Common web server software includes Apache HTTP Server, Nginx, and Microsoft Internet Information Services (IIS). These software programs listen for incoming HTTP (Hypertext Transfer Protocol) requests on specific network ports, typically port 80 for HTTP and port 443 for HTTPS (HTTP Secure).

Beyond simply serving static files like HTML, CSS, and images, web servers can also execute dynamic content. This often involves interacting with databases, running server-side scripting languages such as PHP, Python, or Node.js, and generating personalized content for users. The web server acts as the intermediary, receiving requests, processing them (sometimes involving other applications), and returning the appropriate response to the client. Security is a crucial aspect of web server management, involving measures to protect against unauthorized access, data breaches, and denial-of-service attacks.
