I am trying to allow external access to Outlook Web Acces (hosted on exchange server 2003 on the LAN) through the apache web server on RedHat distro (also on the LAN). I want to use a domain name like webmail.company.com to go directly to the login and then to webmail. So, users will be accessing this domain name which will hit the apache server (firewall already port forwarding) and the apache server will forward this to the exchange server. I have seen in other articles VirtualHost configs with ProxyPass and SSL but none of them seem to work.

I was able to use a series of ProxyPass statements in order to access OWA. So far this works...kinda... The login prompt comes up and after you login the frames for the page load but the individual pages do not. Does anyone have any idea why this is? The ProxyPass statements I used are:

ProxyRequests Off
ProxyVia On

ProxyPass /exchange http://exchangesvr/exchange
ProxyPassReverse /exchange http://exchangesvr/exchange
ProxyPass /exchweb http://exchangesvr/exchweb
ProxyPassReverse /exchweb http://exchangesvr/exchweb
ProxyPass /public http://exchangesvr/public
ProxyPassReverse /public http://exchangesvr/public
ProxyPass /iisadmpwd http://exchangesvr/iisadmpwd
ProxyPassReverse /iisadmpwd http://exchangesvr/iisadmpwd
SetOutputFilter proxy-html

i have put this but a receive a 403 error.
Also in the logs i have see this:

[Fri Feb 11 18:27:11 2005] [warn] proxy: No protocol handler was valid for the U
RL /exchange. If you are using a DSO version of mod_proxy, make sure the proxy s
ubmodules are included in the configuration using LoadModule.

Can you please post your complete apache install and config?
Thanks

I'm working on the same thing with Apache2. This guy seems to have accomplished it, but final config is unclear. http://www.issociate.de/board/post/1...and_mod_proxy_(reverse_proxy).html
