File README of Package apache2-mod_proxy_msrpc


mod_proxy_msrpc intends to make Apache work in a reverse proxy setup in front 
of a MS Exchange server offering Outlook Anywhere services. Without it, Apache 
would block any Outlook Anywhere requests for reasons documented very well in
The code has been successfully tested on Apache 2.4.x, in use with following 
software combinations:
  - mail exchange works over WAF with Exchange Server 2007 in combination with 
    Outlook 2007, 2010 and 2013. The offline address book and calender 
    synchronization seem to use different protocols independent from Outloook 
  - mail exchange, Offline Address Book and calender synchronization works with 
    Exchange Server 2010 and Exchange Server 2013 in combination with Outlook 
    2007, 2010 and 2013.

In order to use the plugin you need to enable it in your setup using
  a2enmod proxy_msrpc
with root privileges.
Next thing is to create a virtual host in Apache to serve as reverse proxy.
Please take a look at the vhost-exchange.template file provided with this
package as a reference. The crucial directive of this plugin is
