Apache2 Webserver Custom Footer


Due to the continued lack of a stable and fast home Internet connection we have been forced to mirror one of our principal Websites to an American hosting company.

Since there are now 2 domains involved, i.e. we did not move the domain, we wanted a simple way to alert people to the fact that a new mirror site was available to them.   The mirror site is not ideal but is able to serve pages at about 30 Mbits / second, whereas our local webserver can manage a pathetic  0.1 Mbit/second.

Compare this to the previous 500 Mbits/second or faster from our Swiss home and you can see why Marcus is almost in tears.

How to install a custom Apache2 footer

This is the procedure I used on a Linux Mint Server, and Mint is a Ubuntu derivative.


#install security 2 module
apt install libapache2-mod-security2

SecServerSignature 'NB: Webserver mirror at amaus.org, regds Marcus Bennett:'

#restart apache2
systemctl restart apache2.service






And here is the finished product




Meanwhile here at the mirror we have an identical layout and content with of course a standard footer since we don't have the power to change this American hosted system.
