getting Apache2::Request enabled in Ubuntu

Installing the libapreq2 module alone isn’t enough to get Apache2::Request running. Additionally you will need to go to the /etc/apache2/mod-enabled direcorty and sym link in the module to be loaded from /etc/apache2/mods-available

cd /etc/apache2/mods-enabled
ln -s ../mods-available/apreq.load apreq.load
/etc/init.d/apache2 restart
