Subject [users@httpd] Reverse Proxy: Max-Forwards has reached zero - proxy loop?
Date Tue, 09 Jun 2009 08:30:57 GMT
Hello List,

i am trying to access a M$ Exchange Server via a Apache Reverse Proxy.
But i am getting the error: Max-Forwards has reached zero - proxy

I already checked, if some name resolved to itself (which WAS the case
and i fixed it), but it still does not work.

Here is the setup and config:

ppp0 IP: (resolvses to from official dns)
eth0 IP: (LAN IP) and (resolvses
to from apche/internal)

  SSLEngine on
  SSLCertificateFile /usr/local/apache/conf/webmail.example.cert
  SSLCertificateKeyFile /usr/local/apache/conf/webmail.example.key

  SSLProxyEngine on
  RewriteEngine on
  RewriteRule ^/$ /exchange [R]

  ProxyPass /exchange
  ProxyPassReverse /exchange
  ProxyPass /exchweb
  ProxyPassReverse /exchweb

  AddType application/x-httpd-php .php

INTERNET <==== ( =====> Linux/LAMP
<=== ====>  Exchange (

What am i doing wrong here and why does it loop?

Thanks a lot,
