1. A multi-tier application architecture having a middletier comprising:

  • a framework to mediate between an application and a middletier, wherein the framework allows a middletier to execute an object fetched by an application from a cache;

    wherein, when an object becomes stale, the framework repeatedly refreshes the object within a limited number of retries;

    wherein, when an object refresh succeeds, the framework returns the object to the cache and again allows the middletier to execute the object; and

    wherein, when an object refresh does not succeed within a limited number of retries, the framework quits an application in fail-safe way.
