Hi,

I am looking to deploy Apache 2.2 on a Windows box as a reverse-proxy to two servers. I used raw IP addresses to avoid any DNS issues. The following is what I have in httpd.conf on the reverse-proxy.


<VirtualHost *:*>
ProxyPreserveHost On
ProxyHTMLLogVerbose On
ProxyPass /app XX.XX.XX.XX
ProxyPassReverse /app XX.XX.XX.XX
ProxyHTMLURLMap 192.168.122.184 /app
</VirtualHost>

<VirtualHost *:*>
ProxyPreserveHost On
ProxyHTMLLogVerbose On
ProxyPass /backup/app YY.YY.YY.YY
ProxyPassReverse /backup/app YY.YY.YY.YY
ProxyHTMLURLMap YY.YY.YY.YY /backup/app
</VirtualHost>

The first server XX.XX.XX.XX is the main application and the proxy is able to redirect browser requests without any problems. However, the second server is not reachable through the proxy.

I turned on LogLevel Debug and the proxy's error.log has the following.

[Wed Mar 19 22:08:20 2008] [error] [client XX.XX.ZZ.ZZ] File does not exist: C:/Program Files/Apache Software Foundation/Apache2.2/htdocs/backup

Also, the direct access to second server, bypassing the proxy, using YY.YY.YY.YY works fine, both from the browser client as well as from the proxy.

Is there anything I am missing?

Thanks.
