       nginx should not rewrite this line, then the 500 code response body
       was transferred; the bug had appeared in 0.1.29.

    *) Bugfix: some directives of the ngx_http_proxy_module and
       ngx_http_fastcgi_module were not inherited from the server to the
       location level; the bug had appeared in 0.1.29.
