This post guides you on how to configure apache2 to run as a reverse proxy in front of tomcat. The reason I personally use apache2 instead of directly exposing tomcat is because it becomes easy to install SSL certicates and automate their renewal. This is also best practice as it is not recommended to expose your tomcat servlet to the world.

This guide assumes that you have installed DSpace 6, or any other application that you wish to run behind a proxy. It also assumes that it is configured to run on port 8080 which is the default port number for a tomcat installation.
