Reducing Redundant Transmissions in Client Polling Operations Using a Backend Data Grid

A server receives a data request from a client. The request contains contextual information which can be used at a server/datacenter level for providing the requested data. The server uses the contextual information to prepare a response to the request. The server stores the received contextual information in association with the specific client in a data grid, such that an identifier of the client can be used by any server in the datacenter to access the stored information. Subsequent to the storing of the contextual information in the data grid, a second request from the same client is received by any server with access to the data grid. The second request contains the client identifier, but not the contextual information. The server uses the identifier to access the stored contextual information in the data grid, and uses the contextual information to prepare a response to the second request.
