CIMM DEFINITION: The process of copying a Web element (page or ad) for later reuse. On the Web, this copying is normally done in two places: in the user’s browser and on proxy servers. When a user makes a request for a Web element, the browser looks into its own cache for the element; then a proxy, if any; followed by the intended server. Caching is done to reduce redundant network traffic, resulting in increased overall efficiency of the Internet. (Source: IAB)
