Copy the Apache list for this.

You can test ReverseProxy out by trying to connect to your Apache server
on your local network to run Outlook Web Access before you change the
settings on the router.  IE you type instead of

You need to change the httpd.conf configuration I gave you to use the
name or the IP address of the exchange server in the URLs like:

ProxyPass /exchange
ProxyPass /exchange

Also make sure that https works on your exchange server.  What do people
type in now to get to the Exchange server's OWA?  That's what you type
in the http:// or https:// lines after ProxyPass.  Set up https on
Apache and IIS (the Exchange server) so that it will be secure.  Just do
a google search for how to make your own certificate and install it on
these machines.  You can do this with the Microsoft Certificate
Authority also (it's an option in Windows 2000/2003 setup).

Subject: Reverse Proxy Help?

Hello sir,

I know you directed me to the following link:

I want to do this without messing anything up. So could you please let
me know if I am thinking right?

I have a DSL NAT Router which links me to the internet.

Machine 1 - Apache Webserver   -    IP address

Machine 2 - MS Exchange Server -    IP address

My router has the following mapping

www - Http  Port 80
smtp		Port 25
Pop3        Port 110 

Knowing that OWA on Machine Number 2 is by default coming out of Port
80, are you saying that if I included the following in httpd.conf on
Machine 1, then I am okay? 

And secondly, I do not have SSL.CONF Is this something I should have

 ProxyPreserveHost On

ProxyPass /exchange
ProxyPassReverse /exchange
ProxyPass /Exchange
ProxyPassReverse /Exchange
ProxyPass /exchweb
ProxyPassReverse /exchweb
ProxyPass /public
ProxyPassReverse /public
ProxyPass /iisadmpwd
ProxyPassReverse /iisadmpwd

ProxyPass /oma
ProxyPassReverse /oma

Thanks you in advance.
