[users@httpd] Apache as a reverse proxy for Sharpoint 2010

[Ralf.Lutz]

Hi together,

we have a httpd-2.2.3-45 working as a reverse proxy for different backends, 
including Outlook Web Access, everything works fine.

Now we have to set up sharepoint 2010 as a beckend and this makes some 
problems. I get no response in the browser, only 404 errors. The sharepoint 
site is configured without ntlm or ssl for testing.

Here ist my conf-file:

   ProxyRequests Off
   ProxyPreserveHost On

   Header unset WWW-Authenticate
   Header set WWW-Authenticate "Basic realm=\"ww2.heidelberg.de\""


   <Location /proext>
     ProxyPass http://proext.heidelberg.bw-online.de
     ProxyPassReverse http://proext.heidelberg.bw-online.de
   </Location>

This config works for owa, so I thougt, this should work for sharepoint, too, 
but it doens´t.

Has anyone an idea, where the problem could be?

Kind Regards
Ralf Lutz
