[35] When accessing Web pages, most Internet browsers will store on the computer’s own hard drive a temporary copy of all or most of the files that comprise the Web page. This is typically known as a “caching function” and the location of the temporary, automatic copies is known as the “cache”. While the configuration of the caching function varies and can be modified by the user, cached files typically include images and are generally discarded automatically after a certain number of days, or after the cache grows to a certain size.

While the cached file might be in a “place” over which the computer user has control, in order to establish possession, it is necessary to satisfy mens rea or fault requirements as well. Thus, it must be shown that the file was knowingly stored and retained through the cache.
