Configuring Virtual Hosts in Apache

index

The configuration detailed here represents the Apache virtual host configuration which gives the web server administrator the greatest flexibility and freedom for specifying virtual hosts based on both name and port number. Obviously not all configuration directive have been included; I didn't want to confuse the issue by including a full httpd.conf/httpsd.conf file -- only the directive which must or should be specified when configuring virtual hosts.

My second disclaimer is that httpd.conf files are like anything else in the sysadmin world-- everyone has their own individual preferences. My configurations are based on the following principles:

Every user's web path resides in their home directory tree
Each user's logs reside in a log directory in the user's home directory tree
The cgi-bin directory is script aliased to prevent improper web access to the CGI files
The images directory is aliased for ease of access and to prevent web visitors from scanning through indexes of image files
CGI has been specifically allowed outside the user's cgi-bin directory, but can be just as easily disabled (by removing ExecCGI from the access Options).
