Just wondering ( I don't see it in the docs ) if one can define "variables" in
the Apache conf. files.
i.e. I have seen people write something along the lines of
%{HTTP_REFERER}
in their conf file.
So.. is there any support for a sort of variable substitution within the conf
file.. e.g.
%DIR=/usr/local/
and then
ServerRoot %{DIR}
I'm doubting it but this would be nice.

How does this work for you: it depends on what you want.
If you want certain URLs to be revalidated with every request, you should follow Joshua's advice and make sure that those resources
are served with Cache-Control: must-revalidate. If the source server is an Apache and the resources are static files, you can
probably use mod_headers (Header set or Header append) to achieve this. The downside of this strategy is that it makes caching the
resource on the reverse proxy more or less pointless.
If you can accept a certain delay between the time where the source is updated and the update becomes effective for the client,
playing with CacheDefaultExpires may get you there. The RP cache will be revalidated every time the cache entry becomes stale, and
you can determine the interval using CacheDefaultExpires. That will reduce the number of requests that need to be forwarded all the
way to the source.

Hello Axel-Stéphane,
If I can follow what you are trying to tell me, I should add the "expiresactive on" directive on the source server instead of the
caching server?
