[Koha-devel] Apache 2.4 env vars

[David Cook]

Paul:

Yes, I do believe that I said that Apache ServerName != SERVER_NAME (unless
UseCanonicalName is turned on it seems) :p.

So, I've just gone and run up a new install Koha (via the packages) on a
virtualized Ubuntu 14.04, which uses Apache 2.4.

I just dumped out the SERVER_NAME and SERVER_PORT environmental variables,
and... they had the IP address and the port number 80 in them respectively.
I got the exact same result on OpenSuse using Apache 2.2. 

So if those environmental variables are empty for you... something is
probably wrong with your Apache configuration.
