System and method for providing an actively invalidated client-side network resource cache

A method comprising:

• configuring, by use of a data processor, a client to request, for a client application, data associated with an identifier from a server;
• configuring, by use of a data processor, the server to provide the data associated with the identifier, the data being subject to subsequent change, the server being further configured to establish a queue associated with the identifier at a scalable message queuing system, the scalable message queuing system including a plurality of gateway nodes configured to receive connections from client systems over a network, a plurality of queue nodes containing subscription information about queue subscribers, and a consistent hash table mapping a queue identifier requested on a gateway node to a corresponding queue node for the requested queue identifier;
• configuring the client to subscribe to the queue at the scalable message queuing system to receive invalidation information associated with the data;
• configuring the server to signal the queue of an invalidation event associated with the data;
• configuring, by use of a data processor, the scalable message queuing system to convey information indicative of the invalidation event to the client;
• and
• configuring the client to re-request the data associated with the identifier from the server upon receipt of the information indicative of the invalidation event from the scalable message queuing system.

A non-transitory machine-useable storage medium embodying instructions which, when executed by a machine, cause the machine to:

• configure a client to request, for a client application, data associated with an identifier from a server;
• configure the server to provide the data associated with the identifier, the data being subject to subsequent change, the server being further configured to establish a queue associated with the identifier at a scalable message queuing system, the scalable message queuing system including a plurality of gateway nodes configured to receive connections from client systems over a network, a plurality of queue nodes containing subscription information about queue subscribers, and a consistent hash table mapping a queue identifier requested on a gateway node to a corresponding queue node for the requested queue identifier;
• configure the client to subscribe to the queue at the scalable message queuing system to receive invalidation information associated with the data;
• configure the server to signal the queue of an invalidation event associated with the data;
• configure the scalable message queuing system to convey information indicative of the invalidation event to the client;
• and
• configure the client to re-request the data associated with the identifier from the server upon receipt of the information indicative of the invalidation event from the scalable message queuing system.
