Abstract
A method for caching images in a virtual environment uses hash tables to store information about an application or window and to store updated images. Suitable areas of applications or windows are fixed relative to the window for many cases, and also include a relatively small number of possible display statuses. Hash tables are used on an agent side and a client side to track previous image updates. When an updated image is determined to be already stored in a cache, the agent side can transmit a hash identifying the image to the client side, and the client side can update the display with the cached image.
