Web servers are an essential component of the internet infrastructure. They play a crucial role in delivering web pages and other web resources to users all around the world. In this article, we will explore how web servers work, with examples to help you better understand the process.

What is a Web Server?

A web server is a software application that runs on a computer and responds to requests from clients, which are typically web browsers. It receives requests for web resources, such as HTML documents, images, videos, and more, and delivers them back to the client over the internet.

How Does a Web Server Work?

A web server follows a client-server model. When you type a URL or click on a link in your browser’s address bar, your browser sends an HTTP request to the appropriate web server. Let’s go through the steps involved in this process:

  • Step 1: The client sends an HTTP request to the web server.
  • Step 2: The request contains information about the resource being requested (e.g., URL) and other parameters.
  • Step 3: The web server receives the request and processes it.
  • Step 4: If the requested resource exists on the server, it retrieves it from disk or memory.
  • Step 5: The server then prepares an HTTP response with the requested resource.

In addition to delivering static files like HTML documents or images, web servers can also execute scripts or interact with databases to generate dynamic content. This allows websites to provide personalized experiences or perform complex operations based on user input.


Let’s say you want to visit a website called When you enter this URL in your browser and hit enter, your browser sends an HTTP request to the web server that hosts the domain.

The web server receives the request and checks if the requested resource, such as the homepage, exists on its system. If it does, the server retrieves the HTML file from disk or memory.

The server then prepares an HTTP response with the HTML content. This response includes a status code (e., 200 for successful requests) and headers containing additional information about the response.

Finally, the web server sends this response back to your browser over the internet. Your browser receives the response and renders it, displaying the website’s content on your screen.


Web servers are essential for delivering web resources to users. They receive requests from clients, process them, retrieve the requested resources if available, and send back an HTTP response. Understanding how web servers work is crucial for anyone interested in building or maintaining websites.

Now that you have a better understanding of web servers’ functioning, you can explore further and learn more about advanced concepts like load balancing, caching, and security measures that enhance their performance and reliability.
