Thanks again for your suggestions, Matt. I got it working by using a slightly different approach. My guess is that apache had an issue (again, only with multiple servers) when the first virtual server was a redirect. By changing the httpd.conf section included earlier to the following one (note the subtle differences), everything works correctly now: ... ServerName www.mydomain.com:80 ... NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/public_html ServerName www.mydomain.com </VirtualHost> <VirtualHost *:80> Redirect permanent / http://www.mydomain.com/ ServerName mydomain.com </VirtualHost> <VirtualHost *:80> DocumentRoot /var/www/partner1 ServerName partner1.mydomain.com </VirtualHost> ...
