Hi Gena,

That staging is not working from your side is because of an ACL in Apache.
I can not enable the debug option because I use the RPM and it is not enabled by default:
Starting nginx: 2009/09/15 10:26:21 [emerg] 17939#0: unknown log format "debug" in /etc/nginx/nginx.conf:55

The logfiles are the same like the one I send:

[/code]

The strange thing is: HEAD works with a redirect in a normal Apache setup but with a Nginx redirect setup (see my config above here) I get a 404 from the Apache and Nginx, I think the request isn't correctly entering Apache.
Can it be a change in the HTTP 1.0 and HTTP1.1 diffirence?
