Umm. I haven't worked with mod_proxy before. But how is this different from
using ALIAS (aka mod_alias)? Have you considered that?

Extracts from apache docs:

This module provides for mapping different parts of the host filesystem in
the document tree, and for URL redirection.
Example:    Alias /image /ftp/pub/image

A request for http://myserver/image/foo.gif would cause the server to return
the file /ftp/pub/image/foo.gif."

where as apache docs for mod_proxy says:

This module implements a proxy/cache for Apache. It implements proxying
capability for FTP, CONNECT  (for SSL), HTTP/0.9, HTTP/1.0, and (as of
Apache 1.3.23) HTTP/1.1. The module can be configured to connect to other
proxy modules for these and other protocols.
