What is a Web Server

Database servers, file servers, web servers, and mail servers use various kinds of server software. All these applications can access the files on the physical server to use for various purposes.

In simple terms, the servers serve websites on the web. The web servers perform the role of a middleman between the client machines and the server. When users request content, the webserver pulls out content from the server and delivers it to the internet.

But serving many users simultaneously is one of the biggest challenges faced by web servers. Files are written in various programming languages, such as Python, Java, PHP, and others. These files are processed by web servers and transformed to static HTML files for serving them to the user’s web browser.

Apache Web Server: How Does It Work?

Apache Web Server

Apache is not a physical server. Instead, it is software running on the HTTP server. Like we said, its role is to connect the server and the website visitor’s browser as it delivers the files back and forth. Apache is also compatible with all operating systems, be it Unix or Windows.

When a web user must load a page on the site, the browser sends a request to Apache, and it then responds with the files requested.

The client and the server connect through HTTP protocol. Apache server helps in maintaining smooth and secure communication between the two.

The best thing about Apache is it is customizable due to its open-source infrastructure. This is the reason users and web developers can adapt the source code based on the type of website they are developing.

Apache also comes with a wide range of modules that let server administrators turn off and on the additional functionalities. You will find modules for URL writing, website caching, or password authentication.

Why Choose Apache?

Between lightSpeed and Apache web server, since Apache is an open-source software it means the source code can be collaborated and viewed for free. This is also the reason it is popular among the developers who have created and configured the modules for applying them to certain features and enhancing their core functionality.

Apache server is mostly a backend thing.
