Reverse Proxy to a ColdFusion Site using IBM HTTP Server 1.3

[webfor...@macromedia.com]

We are trying to set up a reverse proxy using IBM HTTP Server 1.3.6 to
render a CFMX 6.1 site and are having some difficulties.

Here is how we tried to set up the reverse proxy, in the httpd.conf file
for the http server we added the following lines:

ProxyRequests Off
ProxyPassReverse /Test/ http://qdn02:8579
ProxyPass /Test/ http://qdn02:8579

Where /Test/ is an alias to a folder on the proxy server and
http://qdn02:8579 is a ColdFusion site hosted IIS 5.

When I access http://proxyserver/Test in a browser, I get the following
error:

Not Found
The requested URL /user/login.cfm was not found on this server.

The default document for the site http://qdn02:8579 is called index.htm and
looks like this:

......

<frameset rows="1,*" border="0" frameborder="No" bordercolor="#000000">
<frame name="tp"
src="/WGIncludes/HTML/bkng.htm"
scrolling="no"
frameborder="0"
noresize
marginheight="0"
marginwidth="0"
bordercolor="#000000">
<frame name="body"
src="/start.cfm"
scrolling="auto"
frameborder="0"
noresize
marginheight="0"
marginwidth="0"
bordercolor="#000000">
</frameset>

..............

The start.cfm page detects that the user is not logged in and redirects
them to the user/login.cfm page with a cflocation tag that looks like this:

<cflocation addtoken="Yes" url="/user/login.cfm">

Any ideas?
