The changes were largely the removal of a lot of common
code for <Directory>s and <VirtualHost>s to other files
and the addition of Includes. I then tightened up some
<RewriteRule>s and <RewriteCond>s, and added some
<IfDefine> so I don't have to edit the file as often.
And I added SSL for one virtual host, and bought a
certificate.
Remember -- the httpd configuration and the web data
itself are exactly the same on both boxes, except
for the IP addresses.
Mike.
