if(is_admin())
{
    function hcsem_cdn_callback($buffer) {return str_replace(‘googleapis.com‘, ‘useso.com‘, $buffer);}
    function hcsem_buffer_start() {ob_start("hcsem_cdn_callback");}
    function hcsem_buffer_end() {ob_end_flush();}
    add_action(‘init‘, ‘hcsem_buffer_start‘);
    add_action(‘shutdown‘, ‘hcsem_buffer_end‘);
}
