nginx-0.1.24-RELEASE import

    *) Feature: the ngx_http_ssi_filter_module supports the QUERY_STRING
       and DOCUMENT_URI variables.

    *) Bugfix: the ngx_http_autoindex_module may some times return the 404
       response for existent directory, if this directory was used in
       "alias" directive.

    *) Bugfix: the ngx_http_ssi_filter_module ran incorrectly for large
       responses.

    *) Bugfix: the lack of the "Referer" header line was always accounted
       as valid referrer.
