摘要:
A client assistant, sometimes called a browser helper, runs on a client computer. The client assistant monitors a user's browsing activities and infers one or more next documents that are most likely to be requested by the user. The client assistant attempts to locate a fresh copy of the inferred next document within a client cache. If a fresh copy of the inferred document is not found in the client cache, the client assistant submits a document download request to a document server.
