Apache Reverse Proxy, Multiple unclustered Mail Servers, iwaredir.nsf as redirector

HCL Notes/Domino 8.5 Forum (includes Notes Traveler)

Subject: Apache Reverse Proxy, Multiple unclustered Mail Servers, iwaredir.nsf as redirector

Feedback Type: Question

Product Area: iNotes - Full mode

Technical Area: Customization

Platform: Windows

Release: 8.5.2

Reproducible: Always

Goal: to have users access email from internet using iNotes.
Setup:Apache as reverse proxy, iwaredir.nsf setup for mailfile redirection
What works currently:
1) user goes to webmail.domain-name.com:8080
2) gets the login screen for authentication
3) gets authenticated to correct mail server via iwaredir redirect db

What fails:
4)URL returned from step 3 always contains internal.domain-name.com:8080/mail/mailfilename.nsf (this is incorrect because the internal servername is just internal.domain-name.com without the :8080)

I can get around this if I remove the :8080 when I am inside the network, but this ALWAYS fails from outside the network. So, I know this is not going through my proxy server.
I am also setting a MailServer cookie (AutoLogin form in iwaredir.nsf in the $$HTMLHead field. Code: @SetHTTPHeader("Set-Cookie"; "MailServer=" + lwrwmrMailServer);) to capture the mailserver and telling Apache where to go, but ALL my Apache lines of code are being ignored. I can provide my complete conf file via email upon request, but I am posting a few lines that I think are not working as they are supposed to.

My question is:
1) has anyone been able to successfully setup multiple mail servers that are not clustered to work with Apache and redirect in 8.5.2? If so, can you share your rewriterule and rewritecond directives?
Your help is appreciated in advance. Thank you!

conf file code:
<VirtualHost *:8080>
ServerName webmail.domain-name.com:8080
ServerAdmin webmaster@domain-name.com
ServerAlias webmail.domain-name.com
DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs"

ProxyPass / http://webmail.domain-name.com/iwaredir.nsf
ProxyPassReverse / http://webmail.domain-name.com/iwaredir.nsf
