Unofficial advice is to try looking into error log, it is expected to contain details. In this particular configuration I see at least the following problems: - $http_host is used, but Host header won't be available in case of forward proxy; $host is to be used instead, it will also contain host from the request line. - $request_uri already includes request arguments, "$is_args$args" part is not needed. -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
