US 6,807,606 B2 · Distributed execution coordination for web caching with dynamic content

Abstract

A system and method are disclosed, according to which, the responsiveness of client/server-based distributed web applications operating in an object-oriented environment may be improved by coordinating execution of cacheable entries among a group of web servers, operably coupled in a network. In an exemplary embodiment, entries are considered to be either commands or Java Server Pages (JSPs), and the system and method are implemented by defining a class of objects (i.e., CacheUnits) to manage the caching of entries. An entry must be executed before it can be stored in a cache. Since this is computationally costly, each cacheable entry has an associated coordinating CacheUnit, which sees to it that only one CacheUnit executes an entry. Once the entry has been executed, a copy of it resides in the cache of the coordinating CacheUnit, from which it can be accessed by other CacheUnits without having to re-execute it.

Dependent claims

A system supporting distributed web applications, comprising:

first and second cache
a coordinating CacheUnit adapted to receive a cacheable entry and to respond to a request for the cacheable entry by transmitting that cacheable entry if it is present in the first cache, or by first executing the cacheable entry and placing it in the first cache if it is not already present in the first cache;
and
a requesting CacheUnit adapted to retrieve the cacheable entry if it is present in the second cache, or to request the cacheable entry from the coordinating CacheUnit if it is not present in the second cache;
and
wherein the cacheable entry comprises a command or server page, and if the cacheable entry is a server page that is not present in the first and second cache, the coordinating CacheUnit allows the requesting CacheUnit to execute the server page and place it in the second cache before placing it in the first cache, in lieu of the coordinating CacheUnit executing the cacheable entry as a command.
