Reverse Proxying OWA

[Adam Wenner]

i know you have received a lot of mail regarding reverse proxying OWA, i have read all these and still have no luck, so i come to you, the experts

i set up a reverse proxy on one machine that is made to proxy multiple hosts, therefore each host is contained in a virtual host, the one for exchange is on port 443 (to allow https access to be proxied)

if i open a connection directly to my exchange server at https://exchangeip/exchange/

i am presented with a login prompt

when i open a connection to the reverse proxy with
https://revproxyip/exchange/

i am given an error reading
"The connection to revproxyip has unexpectedly terminated" in firefox (ie simply gives me a 404 error page)

the exchange server is not using NTLM authentication because of problems with proxying that

the conf file for the 443 virtual host is contained below



<VirtualHost *:443>

the commented out rewrite rules will be uncommented, i just wanted to make sure they were not the problem

this apache server is v2.0.52 and has mod_ssl installed with no changes to the SSL conf, is this where i have to change something


thanks for your help, cause im kinda clueless at this point
