Every time you open a website, a web server is working behind the scenes to deliver that page to your screen. Whether it’s a blog, an e-commerce store, or a streaming platform — all depend on web servers. In this guide, we’ll break down what a web server is, how it works, and which types are most popular among developers in 2025.
What Is a Web Server?
When you type a website address (like infofusionhubs.com), your browser sends a request to the web server, which responds with the page content.
Example
:You → Browser → Request → Web Server → Response → Website Loads
How Does a Web Server Work?
- User Request: A visitor types a URL or clicks a link.
- DNS Resolution: The domain is translated into an IP address.
- Server Processing: The web server fetches the requested data.
- Response Sent: The server delivers the webpage to the user’s browser.
