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.
