nginx 0.6.36
*) Change: now the "Invalid argument" error returned by
setsockopt(TCP_NODELAY) on Solaris, is ignored.
*) Change: now POSTs without "Content-Length" header line are allowed.
*) Feature: the "try_files" directive.
*) Feature: the --with-pcre option in the configure.
*) Feature: the "if_modified_since" directive.
*) Feature: the "$cookie_..." variables.
*) Feature: the "$arg_..." variables.
*) Bugfix: compatibility with Tru64 UNIX.
Thanks to Dustin Marquess.
*) Bugfix: a "ssl_engine" directive did not use a SSL-accelerator for
asymmetric ciphers.
Thanks to Marcin Gozdalik.
*) Bugfix: in a redirect rewrite directive original arguments were
concatenated with new arguments by a "?" rather than an "&";
the bug had appeared in 0.1.18.
Thanks to Maxim Dounin.
*) Bugfix: nginx could not be built on AIX.
*) Bugfix: a double response might be returned if the epoll or rtsig
methods are used and a redirect was returned to a request with
body.
Thanks to Eden Li.
*) Bugfix: a segmentation fault might occur in worker process if
"resolver" directive was used in SMTP proxy.
*) Bugfix: fastcgi_store stored files not always.
*) Bugfix: nginx did not process a FastCGI server response, if the
server send too many messages to stderr before response.
