Apache


An Apache HTTP server is a program running on a server connected to an internet network that delivers individual web pages to browsers. This widely used web server is open-source software, making it available to everyone for free.

The Apache web server is also structured into many modules. Therefore, it provides a high level of customisation to specific needs. It is also a multi-platform software, so it works with Linux, Windows, macOS, and other operating systems.

Apache is the basic building block for creating dynamic websites, together with PHP and MySQL. It supports many programming languages (e.g., Perl or Python) and various forms of authentication. In addition, it can create so-called traffic logs that are used to detect problems on the site or for web analytics.

An Apache server ran approximately 69% of sites in 2005. However, this share dropped to 40% in 2018.
