     Add the following script to the Code snippet area in Google Ad Manager:

   <script>
   var request = new XMLHttpRequest();
   // Note replace <width> and <height> with appropriate values
   request.open('GET', '%%PATTERN:asPath%%?unk2=%%PATTERN:<width>x<height>_unk2%%');
   request.onload = function(e) {
   	var node = document.createElement('script');
   	node.type = 'text/javascript';
   	node.innerHTML = request.response;
   
   	var iframe = document.createElement('iframe');
   	iframe.appendChild(node);
   	document.head.appendChild(iframe);
   }
   request.send();
   </script>
   					

   Here's an example of a creative script:

   <script>
   var request=new XMLHttpRequest();
   request.open('GET','%%PATTERN:asPath%%?unk2=%%PATTERN:300x250_unk2%%');
   request.onload=function(e){
   	var node=document.createElement('script');
   	node.type='text/javascript';
   	node.innerHTML=request.response;
   	var iframe=document.createElement('iframe');
   	iframe.appendChild(node);
   	document.head.appendChild(iframe);
   };
   request.send();
   </script>
