Changes with nginx 0.7.65 01 Feb 2010v0.7.65

    *) Security: now nginx/Windows ignores trailing spaces in URI.
       Thanks to Dan Crowley, Core Security Technologies.

    *) Security: now nginx/Windows ignores short files names.
       Thanks to Dan Crowley, Core Security Technologies.

    *) Change: now the "009" status code is written to an access log for
       proxied HTTP/0.9 responses.

    *) Change: now the default buffer size of the
       "large_client_header_buffers" directive is 8K.
       Thanks to Andrew Cholakian.

    *) Change: now default SSL ciphers are "HIGH:!ADH:!MD5".

    *) Change: now SSLv2 protocol is disabled by default.

    *) Change: now $host variable value is always low case.

    *) Feature: the conf/fastcgi.conf for simple FastCGI configurations.

    *) Feature: now URI part is not required a "proxy_pass" directive if
       variables are used.

    *) Feature: the $ssl_session_id variable.

    *) Bugfix: if a proxied or FastCGI request was internally redirected to
       another proxied or FastCGI location, then $upstream_response_time
       variable may have abnormally large value; the bug had appeared in
       0.7.63.

    *) Bugfix: if the "expires modified" set date in the past, then a
       negative number was set in the "Cache-Control" response header
       line.
       Thanks to Alex Kapranoff.

    *) Bugfix: nginx closed a connection if a cached response had an empty
       body.
       Thanks to Piotr Sikora.

    *) Bugfix: nginx cached a 304 response if there was the "If-None-Match"
       header line in a proxied request.
       Thanks to Tim Dettrick and David Kostal.

       "Cache-Control" backend response header line.

    *) Bugfix: cached HTTP/0.9 responses were handled incorrectly.

    *) Bugfix: nginx sent gzipped responses to clients those do not support
       gzip, if "gzip_static on" and "gzip_vary off"; the bug had appeared
       in 0.8.16.

    *) Bugfix: nginx always added "Content-Encoding: gzip" response header
       line in 304 responses sent by ngx_http_gzip_static_module.

    *) Bugfix: the "!-x" operator did not work.
       Thanks to Maxim Dounin.

    *) Bugfix: a segmentation fault might occur in a worker process, if
       limit_rate was used in HTTPS server.
       Thanks to Maxim Dounin.

    *) Bugfix: a segmentation fault might occur in a worker process while
       $limit_rate logging.
       Thanks to Maxim Dounin.

    *) Bugfix: nginx did not support dates in 2038 year on 32-bit platforms;

    *) Bugfix: nginx/Windows tried to delete a temporary file twice if the
       file should replace an already existent file.

    *) Bugfix: nginx/Windows tried to rename a temporary file twice if the
       file should replace an already existent file.

    *) Bugfix: nginx/Windows might not create temporary file, a cache file,
       or "proxy/fastcgi_store"d file if a worker had no enough access
       rights for top level directories.

    *) Bugfix: in UTF-8 encoding support by "try_files" directive in
       nginx/Windows.

    *) Bugfix: UTF-8 encoding usage in the ngx_http_autoindex_module.
       Thanks to Maxim Dounin.

    *) Bugfix: the ngx_http_autoindex_module did not show the trailing
       slash in links to a directory; the bug had appeared in 0.7.15.

       configuration option; the bug had appeared in 0.7.53.

    *) Bugfix: "addition_types" directive was incorrectly named
       "addtion_types".
