The HTML request with the DOM snapshot is transmitted to an HTML server. Subsequently, a request for the DOM snapshot is transmitted from the client computer to the HTML server. The client computer receives an HTML response from the HTML server. The HTML response HTML response includes the DOM snapshot. An image is generated on a display of the client computer using the DOM snapshot from the HTML response.
