Fw: Apache2 Proxy and Domino Http Server Webmail Redirect

[scott . pichelman]

Hi,

I have been trying to get apache's modproxy(ProxyPass/Reverse) or even Modrewrite(RewriteCond/Rules) to work properly with Domino's WebmailRedirect.nsf file.

Here is a Notes forum Post that hopefully explains the problem I am having in a nutshell:
http://www-10.lotus.com/ldd/nd6forum.nsf/55c38d716d632d9b8525689b005ba1c0/175d0edd0639071485256e5c000915d4?OpenDocument

An explaination of my scenario below:
All behind our Firewall - PIX515:

        User(Internet) --> FW --> Apache2 WebServer(DMZ) --> Domino Http Server(COMM-different network)

Starting from the backend first...
The domino Web server is running on  port 81 and it's Home URL is "/DominoWe.nsf". ( I believe this file has code or references the Webmail redirect db/code)
We are using an IBM/Lotus supplied Domino Webmail "redirect" called "WebAccessRedirect650.ntf".
If I use the Domino webserver address & port to access webmail it works fine.
A single sign-on and we are redirected to our mail file without any problems.(The redirect takes the info given with username/pwd from names.nsf and any other files & directs the browser to the mail/*.nsf and loads up webmail interface/template)

However, it's get's more complex as you know when we add Apache2 and its Reverse Proxy into the mix.
I have tried using modrewrite w/ rewriterules and I get the same result. ( I tried your method and many others as well)

RewriteEngine on
RewriteLog "/var/log/httpd/rewrite.log"
RewriteLogLevel 2
RewriteCond %{REQUEST_URI} ^/
RewriteRule /(.*) http://203.57.228.7:81/$1 [P]

And with a Pound Proxy added to the configuration, just these two Proxy directives worked for me!

ProxyPass / http://203.57.228.7:81/
ProxyPassReverse / http://203.57.228.7:81/

The IP's listed above are of course the backend Domino Server.
So, as you can see I didn't need modrewrite w/ rewriterules or rewriteconditions.
The reason why is because a used another reverse proxy called "Pound".
URL located below:
http://www.apsis.ch/pound/

Then, for the above ProxyPass/Reverse directives I had the IP and port of the Pound Proxy and the Pound Proxy had the values of the Domino server:

Apache:
ProxyPass / https://webmail.weirslurry.com:8080/
ProxyPassReverse / http://webmail.weirslurry.com:8080/

Pound:
ListenHTTPS 66.170.10.6,8080
BackEnd 203.57.228.7,81,1

Another rudimentary  diagram below:
User(Internet) --> FW --> Apache Web Server/Proxy & Pound Proxy on same machine(DMZ - behind FW) --> Domino Http Server(COMM-another different network behind FW)

So, somehow the addition of the Pound Proxy helped the Http headers/URI/URL's,etc understand teh DominoWEbmailRedirect in Domino Http so it would ask for our username and pwd "only" once and not reveal the IP address of the backend Domino server after serving up the webmail redirect!?!
I know it sounds strange, but it works.

In conclusion, my issue is with the Domino Redirect.
If I could write  home-grown html, php, perl, jsp or ? script/code with my own "redirect" I would think that apache would behave better?
I found some examples of creating a work-around or a homegrown solution in the Notes forums where others have had the same problem but the explanations & answers weren't clear for me.
Here are some examples:
http://www-10.lotus.com/ldd/nd6forum.nsf/55c38d716d632d9b8525689b005ba1c0/87423972d7b74bca85256dec0059a08d?OpenDocument
http://www.notestips.com/80256B3A007F2692/1/NAMO5RX3PX
None of which seem to work for me!?!

And this last one I would like to try but haven't given it any thought or know how to start w/ Lotus forms/agents...

Should I be using vhosts and then add some rewriterules together in order to remedy my problem?
 
If you are still confused I can allow you access the Domino Web server Webmail front-end I am working on from the net.
I appreciate any feedback, thanks!
