Apache2 Module installed but not loaded

I came across a customer recently that had a module installed on their apache2 installation, but they couldn’t understand why it wasn’t loaded. In this case it was the filter module.

[root@box ~]# yum provides /usr/lib64/httpd/modules/mod_filter.so

You can activated it by adding following line to httpd.conf;

It was simple to install just throw this in your httpd.conf

LoadModule filter_module modules/mod_filter.so

Job done.
