Caching can be employed at many levels within a computer system such as at the processor level, within databases, Web browsers, servers, and proxies. For many software applications, system support for caching is insufficient for improving performance; application-level cachiig is needed as well. This paper provides an overview of techniques for building application-level caches. We also describe how we deployed application-level caching for improving performance in real settings. One of the novel features of our caching system is its method for automatically recomputing cached entities comprised of sets of objects based on object lifetimes. We also provide support for multiple contexts, transactions,locking, and application-specific cache API functions.
