NAME Apache::Layer - Layer content tree over one or more others. SYNOPSIS #httpd.conf PerlTransHandler Apache::Layer # anywhere you can configure a location PerlSetVar apache_layer_location /project/images PerlSetVar apache_layer_path /dir1/root;/dir2/root DESCRIPTION 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. COMMON PROBLEMS 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. . AUTHOR Simon Matthews REVISION $Revision: 1.6 $ COPYRIGHT Copyright (C) 1998 Simon Matthews. All Rights Reserved.
