Apache::Layer - Layer content tree over one or more others.
#httpd.conf PerlTransHandler Apache::Layer # anywhere you can configure a location <Location /project/images> PerlSetVar apache_layer_location /project/images PerlSetVar apache_layer_path /dir1/root;/dir2/root </Location>
This module is designed to allow multiple content trees to be layered on top of each other within the Apache server.
I developed this module because we produce lots of web sites where a high proportion of the site content is common. But where specific pages / images are tailored to the specific project. This module allows us to layer a sparse directory tree on top of the main complete tree without requiring redirects.
The essence is that it will cause Apache to deliver content from a series of directories in turn.
In some ways Apache::Layer is similar to Apache::Stage however it does not require redirects.
Apache::Layer is relatively simple. The most common problem is not setting the apache_layer_location parameter correctly. As a rule this parameter should ALWAYS match the parameter within the location i.e. <Location /parameter>.
