This module 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 https://issues.apache.org/bugzilla/show_bug.cgi?id=40029.
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 Anywhere.

- 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.
