SEPARATION OF MUTABLE AND IMMUTABLE DATA IN A MEMORY CACHE FOR IMPROVEMENT OF DATA UPDATES

A computer-implemented method, system and computer program product for updating a resource in a cached memory storage are provided. Mutable and immutable components of a resource are generated. The mutable component includes metadata that includes the amount of time the resource persists in the cached memory storage. The immutable component of the resource includes content provided by the source of the resource. A key associated with the resource is generated, where the key is used to access the mutable component and the immutable component in the cached memory storage. The key, the mutable component and the immutable component of the resource are transmitted to the cached memory storage from which the resource is retrieved for display on a client device.
