*) 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.
