nginx自身IP也是192.168.1.216
nginx pagespeed在server里面的配置

location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
        location ~ "^/ngx_pagespeed_static/" { }
        location ~ "^/ngx_pagespeed_beacon$" { }
        location /ngx_pagespeed_statistics { allow 127.0.0.1; deny all; }
        location /ngx_pagespeed_message { allow 127.0.0.1; deny all; }

求破解
