How To Configure An Apache SSL Reverse Proxy on Linux?

What is Apache?

Apache is a free and open-source cross-platform web server software that allows users to deploy their websites on the internet. It was launched in 1995 and has been the most popular web server on the Internet since April 1996.

It acts as an intermediary, intercepting and inspecting incoming client requests before forwarding them to the web server. Reverse proxies can provide additional levels of abstraction, control, security, and performance optimization. They are commonly used for load balancing, web acceleration, and to hide implementation details about the web servers.

What is SSL?

SSL, or Secure Sockets Layer, is a protocol for establishing authenticated and encrypted links between networked computers. Its current iteration is called TLS (Transport Layer Security).
