Abstract
Improvement in perceived user response time for information requests is achieved by preloading information in anticipation of a user request. The preloaded information is stored in a look-ahead cache from which it is presented to a user when it is ultimately requested by the user. If preloaded information is requested by a user, it can be presented almost immediately without the latency of a network retrieval. Techniques for optimizing preloading are disclosed. Flexibility in preloading is achieved by organizing information identifiers into a data structure, such as a stack, for preload retrieval, and by limiting the types of information which can be preloaded and by specifying the order in which information types are accessed. Preloading can be implemented on a wide variety of platforms and can be incorporated in a variety of software processes.
