One aspect of SSL enhanced HTTP transmissions is that they are more resource intensive than the
standard HTTP protocol, so a secure server cannot serve as many pages per second. For this reason it
is often a good idea to minimize the information available from the secure server, especially on a high
traffic Web site.
Important
Do not use name-based virtual hosts in conjunction with a secure Web server as the SSL handshake
occurs before the HTTP request identifies the appropriate name-based virtual host. Name-based
virtual hosts only work with the non-secure Web server.
The configuration directives for the secure server are contained within virtual host tags in the
/etc/httpd/conf.d/ssl.conf
