What kind of thing are these &quot;Apache environment variables&quot; anyway ?<br>
I have been using them extensively within Apache itself, but I still can&#39;t quite \
figure out on what plane they live.   Clearly, they are not &quot;environment \
variables&quot; in the same sense as &quot;cgi-bin environment variables&quot;, and \
not the same thing either as what a &quot;PerlsetVar&quot; does, so what are they \
?<br> <br>
(And I realise that this is more of an Apache httpd question, but I figure that if \
someone should be aware of the httpd internals, there is a good chance of finding \
such a person here).<br> <br>
