Changes with nginx 0.3.8 09 Nov 2005v0.3.8

    *) Security: nginx now checks URI got from a backend in
       "X-Accel-Redirect" header line or in SSI file for the "/../" paths
       and zeroes.

    *) Change: nginx now does not treat the empty user name in the
       "Authorization" header line as valid one.

    *) Feature: the "ssl_session_timeout" directives of the
       ngx_http_ssl_module and ngx_imap_ssl_module.

    *) Feature: the "auth_http_header" directive of the
       ngx_imap_auth_http_module.

    *) Feature: the "add_header" directive.

    *) Feature: the ngx_http_realip_module. directives.

    *) Feature: the new variables to use in the "log_format" directive:
       $bytes_sent, $apache_bytes_sent, $status, $time_gmt, $uri,
       $request_time, $request_length, $upstream_status,
       $upstream_response_time, $gzip_ratio, $uid_got, $uid_set,
       $connection, $pipe, and $msec. The parameters in the "%name" form
       will be canceled soon.

    *) Change: now the false variable values in the "if" directive are the
       empty string "" and string starting with "0".

    *) Bugfix: while using proxied or FastCGI-server nginx may leave
       connections and temporary files with client requests in open state.

    *) Bugfix: the worker processes did not flush the buffered logs on
       graceful exit.

    *) Bugfix: if the request URI was changes by the "rewrite" directive
       and the request was proxied in location given by regular expression,
       then the incorrect request was transferred to backend; bug appeared
       in 0.2.6.

    *) Bugfix: the "expires" directive did not remove the previous
       "Expires" header.

    *) Bugfix: nginx may stop to accept requests if the "rtsig" method and
       several worker processes were used.

    *) Bugfix: the """ and "'" escape symbols were incorrectly handled in
       SSI commands.

    *) Bugfix: if the response was ended just after the SSI command and
       gzipping was used, then the response did not transferred complete or
       did not transferred at all.
