摘要：A processor-implemented method manages a data cache for a computersystem. One or more processors maintain a cache for one or more data resources
requested by a client process. In response to a request from the client process for acached data resource, the processors send a first request to a server process for thedata resource, and a second request to the server process for an indication of whether ornot the data resource has been modified since the data source was most recently cached.Responses to the first or second requests from the server process are compared withthe cached data resources so as to identify whether the response to the second requestis inaccurate. One or more processors disable caching for the data resource in responseto a predetermined number of inaccurate second requests associated with the dataresource being identified.
