Abstract
A server receives one or more hashes from a client, where each of the hashes represents a graphics structure maintained by the client. A first hash is generated from a graphics structure according to a hash algorithm, where the graphics structure is generated from an application hosted within the server, where the graphics structure represents a display output of the application. It is determined whether there is an existing hash from the one or more hashes received from the client that matches the first hash. The first hash is transmitted to the client without sending the graphics structure if there is an existing hash matching the first hash. The first hash is used by the client to identify a graphics structure maintained by the client for rendering a display of the client.
