       if ($http_origin = 'https://www.nide123.com') {
                add_header 'Access-Control-Allow-Origin' $http_origin  always; 
             }
       if ($http_origin = 'https://nide123.com') {
                add_header 'Access-Control-Allow-Origin' $http_origin  always; 
             }
       if ($http_origin = 'https://www.li2345.com') {
                add_header 'Access-Control-Allow-Origin' $http_origin  always; 
             }
       if ($http_origin = 'https://li2345.com') {
