apache2 conf

If i need to make whose server / site changes to apache, do i edit apache2.conf under /etc/apache2 ?

if you need to make "whole" server changes, do edit that apache2.conf file.
if you need to make site specific changes, then,
* if these changes are to be applied to all domains one by one, then,
change ehcp/apachetemplate and ehcp/etc/apache2/apachetemplate.
the 2nd one is when non-ssl config is applied to ehcp.

* if those changes are to be applied to only one or a few of domains, then,
choose that domain, click "edit apache template" in ehcp gui.

Thanks!
