Hi.

Trying to configure a reverse proxy to allow external access to an outlook web access server. I am able to route traffic through the NGINX to the OWA server, present the web page, and place the username & pw into the form. OWA rejects valid username/pwd's with a: "Your session has timed out...." error.

Looking through my custom log files, somehow the session ID and the expired values are munged in the GET & POST process through the proxy. There may be a simple fix that I'm not able to find. Any suggestions will be appreciated!
