Apache HTTP Server
Apache HTTP Server, commonly known as Apache, is a free and open-source web server software developed and maintained by the Apache Software Foundation. It is one of the most widely used web servers globally, serving static and dynamic content over HTTP and HTTPS protocols. Apache is highly configurable and supports a modular architecture through extensions like mod_cache for caching functionality.
Developers should learn Apache for deploying and managing web applications, especially in production environments where reliability and performance are critical. It is essential for hosting websites, APIs, and web services, with caching features like mod_cache improving load times and reducing server load by storing frequently accessed content. Use cases include serving static files, reverse proxying, and integrating with backend technologies like PHP or Python.
