nginx-0.3.28-RELEASE import
*) Feature: the "restrict_host_names" directive was canceled.
*) Feature: the --with-cpu-opt=ppc64 configuration parameter.
*) Bugfix: on some condition the proxied connection with a client was
terminated prematurely.
Thanks to Vladimir Shutoff.
*) Bugfix: the "X-Accel-Limit-Rate" header line was not taken into
account if the request was redirected using the "X-Accel-Redirect"
header line.
*) Bugfix: the "post_action" directive ran only after a successful
completion of a request.
*) Bugfix: the proxied response body generated by the "post_action"
directive was transferred to a client.
