Abstract
A method, system and computer program product for improving performance in connection with requesting resources. A request is sent by a browser to a server to retrieve a resource, where the message includes identifiers and tags associated with blocks of data of the resource which are stored in a cache of the client. If the browser receives a response from the server indicating that the resource has not change since last accessed, the browser will determine if one of the tags associated with the data blocks of the resource stored in the cache differs from the associated tags received in the response message. If there is not a match, then the browser has identified the situation where a block of data of the resource has outdated content which can be updated using the content stored in the data block of another resource in the cache with the same identifier.
