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.
