Abstract
Embodiments of the present invention provide a method, system and computer program product for dual timer fragment caching. In an embodiment of the invention, a dual timer fragment caching method can include establishing both a soft timeout and also a hard timeout for each fragment in a fragment cache. The method further can include managing the fragment cache by evicting fragments in the fragment cache subsequent to a lapsing of a corresponding hard timeout. The management of the fragment cache also can include responding to multiple requests by multiple requestors for a stale fragment in the fragment cache with a lapsed corresponding soft timeout by returning the stale fragment from the fragment cache to some of the requestors, by retrieving and returning a new form of the stale fragment to others of the requestors, and by replacing the stale fragment in the fragment cache with the new form of the stale fragment with a reset soft timeout and hard timeout.
