Hi, I had this problem (proxying Exchange) few month ago, when apache 2.0 was just released...
I was unable with apache 1.3 to proxy my OWA (outlook web access). When i sniffed the connection, i saw that for the login/pass process, Exchange was sending a 401 until he found a valid authentification method. In text authentification, apache 1.3 was able to transmit authentication to exchange, from client on netscape and ie. But with the NTLM authentification, it was impossible to do. Why: When the proxy transmit the first authentification method, if it's refused by exchange, proxy receive 401 and close connection btw backend and proxy, but let the client - proxy connection openned. So when the client send his second authentification method check, the proxy is unable to transmit the request to backend because the connection is closed after the first try. The solution we took here is to use Apache 2.0 which do HTTP/1.1 proxy So with apache 2.0, the backend - proxy connection is kept alive and all the authentication method can be checked. It's now working really well and we reverse proxy Exchange. I hope this will help you Regards, Estrade Matthieu -----Message d'origine----- De�: Graham Leggett [mailto:[EMAIL PROTECTED]] Envoy�: jeudi 3 octobre 2002 15:56 ��: [EMAIL PROTECTED] Cc�: [EMAIL PROTECTED] Objet�: Re: mod_proxy support for exchange 2000 Robin P.

I need to see both sides of the connection to see what is changed on the way through the proxy. Also the flows are very big - can you restrict it to just a single request (or set of requests) that pass and/or fail...?
