nginx 0.6.27 *) Change: now by default the rtsig method is not built on Linux 2.6.18+. *) Change: now a request method is not changed while redirection to a named location via an "error_page" directive. *) Feature: the "resolver" and "resolver_timeout" directives in SMTP proxy. *) Feature: the "post_action" directive supports named locations. *) Bugfix: a segmentation fault occurred in worker process, if a request was redirected from proxy, FastCGI, or memcached location to static named locations. *) Bugfix: browsers did not repeat SSL handshake if there is no valid client certificate in first handshake. Thanks to Alexander V. Inyukhin. *) Bugfix: if response code 495-497 was redirected via an "error_page" directive without code change, then nginx tried to allocate too many memory. *) Bugfix: memory leak in long-lived non buffered connections. *) Bugfix: memory leak in resolver. *) Bugfix: a segmentation fault occurred in worker process, if a request was redirected from proxy, FastCGI, or memcached location to static named locations. *) Bugfix: in the $proxy_host and $proxy_port variables caching. Thanks to Sergey Bochenkov. *) Bugfix: a "proxy_pass" directive with variables used incorrectly the same port as in another "proxy_pass" directive with the same host name and without variables. Thanks to Sergey Bochenkov. *) Bugfix: an alert "sendmsg() failed (9: Bad file descriptor)" on some 64-bit platforms while reconfiguration. *) Bugfix: a segmentation fault occurred in worker process, if empty stub block was used second time in SSI. *) Bugfix: in copying URI part contained escaped symbols into arguments.
