nginx 0.6.21 *) Change: if variable values used in a "proxy_pass" directive contain IP-addresses only, then a "resolver" directive is not mandatory. resolver *) Bugfix: a segmentation fault might occur in worker process if a "proxy_pass" directive with URI-part was used; bug appeared in 0.6.19. *) Bugfix: if resolver was used on platform that does not support kqueue, then nginx issued an alert "name is out of response". Thanks to Andrei Nigmatulin. *) Bugfix: if the $server_protocol was used in FastCGI parameters and a request line length was near to the "client_header_buffer_size" directive value, then nginx issued an alert "fastcgi: the request record is too big". *) Bugfix: if a plain text HTTP/0.9 version request was made to HTTPS server, then nginx returned usual response.
