            expires 30d; 

            access_log off; 

            valid_referers none blocked *.web100.cc web100.cc *.youdao.com *.google.cn *.google.com *.google.com.tw *.google.com.sg *.google.com.hk image.soso.com bing.com cn.bing.com image.baidu.com; 

            if ($invalid_referer){ 

                rewrite ^/ http://ofstack.com/images/return.gif; 

            } 

        }
