Followed the instructions from
http://www.apachetutor.org/admin/reverseproxies and finally ended up
with the new configuration below (this snippet added to the end of the
original httpd.conf). However still it doesn't work. Is there any way to
debug this code to see what the problem is?

LoadFile   /usr/lib/libxml2.so.2
LoadModule proxy_html_module   modules/mod_proxy_html.so

ProxyRequests Off

ProxyPass /test/ http://192.168.231.1/
ProxyHTMLURLMap http://192.168.231.1 /test

<Location /test/>
    ProxyPassReverse /
    SetOutputFilter proxy-html
    ProxyHTMLURLMap /    /test/
    ProxyHTMLURLMap /test /test
    RequestHeader   unset Accept-Encoding
</Location>


Thanks,

Mohammad

Thank you very much. It seems that
http://www.apachetutor.org/admin/reverseproxies is the one I need to
follow to solve the issue. While I'm doing so, I'd like to ask one more
question:

My original requirement is to implement a maintenance page. In other
words, all I need to do is to display a simple page with a simple
message saying that system is down for maintenance when we have to bring
down the back-end server. Not sure if setting up a reverse proxy for
this purpose is a good idea. Is there any other way to achieve the same
goal?

Thanks,

Mohammad

That's only part of the story. If (as Joshua suggests)
you've got a javascript redirect, it can be seriously
challenging: you'll need mod_proxy_html's ProxyHTMLExtended
(for script embedded in HTML), or one of the sed-like
filters (mod_sed, mod_substitute, mod_line_edit) if
it's in a separate .js file.
