Subject: nginx-0.1.23-RELEASE import

    *) Feature: the ngx_http_ssi_filter_module and the ssi,
       ssi_silent_errors, and ssi_min_file_chunk directives. The 'echo
       var="HTTP_..." default=""' and 'echo var="REMOTE_ADDR"' commands are
       supported.

    *) Feature: the %request_time log parameter.

    *) Feature: if the request has no the "Host" header line, then the
       "proxy_preserve_host" directive set this header line to the first
       server name of the "server_name" directive.

    *) Bugfix: nginx could not be built on platforms different from i386,
       amd64, sparc, and ppc; the bug had appeared in 0.1.22.

    *) Bugfix: the ngx_http_autoindex_module now shows the information not
       about the symlink, but about file or directory it points to.

    *) Bugfix: the %apache_length parameter logged the negative length of
       the response header if the no response was transferred to a client.
