Abstract
A processor-implemented method manages a data cache for a computer system. 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 a cached data resource, the processors send a first request to a server process for the data resource, and a second request to the server process for an indication of whether or not 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 with the cached data resources so as to identify whether the response to the second request is inaccurate. One or more processors disable caching for the data resource in response to a predetermined number of inaccurate second requests associated with the data resource being identified.
