Now as the Open-Xchange Server has been set up and the database is running, we have to configure the Apache webserver and the mod_proxy_ajp module to access the groupware frontend. To gain better GUI performance, the usage of mod_expires and mod_deflate is strongly recommended. Those modules will limit the amount of client requests and compress the delivered content.

$ a2enmod proxy && a2enmod proxy_ajp && a2enmod expires && a2enmod deflate && a2enmod headers && a2enmod rewrite && a2enmod proxy_balancer
