http keep alive with post requests issue

[lzilles]

I figured that the location settings have not been used at all.
So now I can see that even for location settings the same error occurs. If I
use keepalive and proxy_set_header Connection "" it works. As soon as I add
"proxy_http_version 1.1" to any context, the POST responses still get
returned directly by the application server...
