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.
