When I make a request via nginx however, the Content-Length header is
no longer present (again using wget):
Connecting to localhost|127.0.0.1|:80... connected.
HTTP request sent, awaiting response...
HTTP/1.1 200 OK
Date: Tue, 23 Aug 2011 18:40:30 GMT
Is there any obvious reason this should be happening, or something I'm
doing wrong? The proxy_pass_header directive in the configuration file
seems to make no difference to the outcome when I uncomment it.
