The Complete 2023 Apache HTTP Server Troubleshooting Guide

The Apache HTTP server has been the world‘s most popular web server software for over two decades. Created in 1995 by Rob McCool at the National Center for Supercomputing Applications, Apache played a pivotal role in the early growth of the web.

Even today, Apache powers over 30% of all active websites – more than rivals like Nginx and IIS. The reliability, performance and open source nature of Apache makes it the preferred choice for many organizations.
