Adding X-Clacks overhead to Apache.

X-Clacks-Overhead is a non-standard HTTP header based upon the fictional work of the late, great, Sir Terry Pratchett.

You can read all about it here...

It is trivial to add to an apache installation. Simply make a file in the apache configuration directory, ( /etc/httpd/conf.d on Fedora, others will be similar).

terrypratchett.conf

<IfModule headers_module>
    Header set X-Clacks-Overhead "GNU Terry Pratchett"
</IfModule>

I love the thought that under the surface, this message is flying around the world — whispered in the wind.
