[users@httpd] Apache 2.0.48 does not reverse proxy BMOVE

[Jacques Bourdeau <J_...@videotron.ca>]

Hi,

I'm trying to configure Apache as a reversy proxy and SSL accelerator 
for Outlook Web Access 2000.

The Internet Explorer interface uses WebDAV for many functions, like 
deleting a message.

Right now, Apache successfully handle methods like PROPFIND and SEARCH, 
but not BMOVE.

Apache do not try to forward the request to the back end server : as 
soon as the BMOVE is received, Apache answers back with a 502 Bad 
Gateway error message built with the IIS headers. The error log contains 
nothing about this error.

Any idea why Apache do not forward the request to the back end server ?

Here is details about my situation :
