  • Method, apparatus, and program for minimizing invalid cache notification events in a distributed caching environment
    Patent number: 7818600
    Abstract: A distributed cache management system that minimizes invalid cache notification events is provided. A cache management system in a sending device processes outgoing cache notification events by adding information about the source server's clock. A cache management system in the receiving device then uses this information to adjust event information once the event is received.
    Type: Grant

  • Method and system for specifying a cache policy for caching web pages which include dynamic content
    Patent number: 6988135
    Abstract: A data processing system and method are described for specifying a cache policy for caching pages which include dynamic content. A user is permitted to request a page to be displayed. The page includes multiple fragments. An application is executed which generates those fragments. The generation of fragments is are unchanged by the caching policy. Each one of the servlets is executed to present a different one of the fragments. Caching of the page fragments can now be processed separately from the execution of the application.

  • Enhanced fragment cache
    Patent number: 6601142
    Abstract: A method for enhanced fragment caching. The method can include identifying in at least one of first and second retrieved page fragments a variable object utilized by the fragment upon execution to produce dynamic content. Separate cache entries can be written for the first and second retrieved page fragments where the first and second retrieved page fragments differ in ways other than an evaluation of the variable object. Otherwise, a single cache entry can be written for both the first and second retrieved page fragments where the first and second retrieved page fragments differ only in the evaluation of the variable object.
