nginx 0.3.28 *) 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.
