ABSTRACT:
The invention provides a method, system and computer program product for caching dynamic portal pages without changing the existing caching proxy infrastructure or the transportation protocol used by providing an advanced caching component. An advanced caching component provides the functionality that additional dynamic page specific cache information is provided as part of the response including the portal page. Each component in the portal that dynamically contributes page fragments to be aggregated to a portal page provides dynamic component specific cache information which includes component specific cache scope and expiration values. The component specific cache scope and cache expiration values are used to calculate dynamic page specific cache information resulting in a common minimum cache scope and a common minimum cache expiration values for a portal page to be aggregated. The dynamic page specific cache information ensures that the minimum cache scope is correctly chosen as contributed from the components and the minimum cache expiration does not exceed any of the component specific cache expiration values.
