The previous behaviour was a bug, as nginx interpreted 
X-Accel-Redirect'ed requests as GET internally, but still used 
original request method in requests to upstream servers.  This was 
fixed in 1.9.10:

    *) Bugfix: proxying used the HTTP method of the original request after
       an "X-Accel-Redirect" redirection.

If you want to preserve original request method, use 
X-Accel-Redirect to a named location.  Much like in case of 
error_page (http://nginx.org/r/error_page), this will preserve URI 
and request method during redirection.
