nginx 0.1.24 *) 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.
