You can find the detailed response to your original message here:

Unfortunately, forum interface is broken and is unable to show it 
in the correct thread.  Consider using the mailing list directly 
instead, see http://nginx.org/en/support.html.

Additionally, it's also unlikely that you'll see this message as 
well, due to the same forum bug.
