Overview

Allow files to be servered from multiple directories within a single URL space

This is sometimes very useful when working with multiple application servers, each with their own set of static files.

Usage:

uri "/request_path/", :handler => MultiDirHandler.new(['/file/path1','/file/path2'])

options:

:cwd, override the server root directory, make sure there is a tmp directory in server root
