What is Apache Web Server?
Apache web server is a free and open-source web server that runs on a broad range of operating systems. Apache’s primary function is to serve web pages and web applications to customers. Apache is an HTTP server that acts as a reliable and efficient medium between the client and the server.
Apache web server provides a platform for web developers to deploy their applications and web pages to the internet. Apache’s functionality includes serving static web pages, dynamic web pages via scripting languages like PHP, and proxying requests.
How Does Apache Web Server Work?
Apache web server works on a client-server model. The clients are the web browsers that request content, while the server is the machine or computer that serves them. Apache’s role is to listen to incoming requests, read them, and then respond with the requested content.
Apache web server uses a request-response protocol for communication between the client and the server. Clients usually request static HTML pages or dynamic pages that are generated by server-side scripting languages, such as PHP or Python. The Apache server reads the request and looks for the requested content on the server’s disk. If the requested content is available, Apache sends it back to the requesting client.
