A method is presented for determining whether to prefetch and cache documents on a computer. In one embodiment, documents are prefetched and cached on a client computer from servers located on the Internet in accordance with their computed need probability. Those document with a higher need probability are prefetched and cached before documents with lower need probabilities. The need probability for a document is computed using both a document context factor and a document history factor. The context factor of the need probability of a document is determined by computing the correlation between words in the document and a context Q of the operating environment. The history factor of the need probability of a document is determined by integrating both the recency of document use and the frequency of document use.

[ What is claimed is:] [1.] A method for determining with a computer whether to prefetch and cache documents, comprising the steps of:recording context data and history data of the documents in a needs list stored in a memory of the computer; said recording step being performed each time a document request is received by the computer;computing a need probability for the documents recorded in the needs list stored in the memory; said computing step computing the need probability for the documents as a function of the recorded context data and history data of the documents; andidentifying those documents in the needs list with the greatest computed need probability to be prefetched and cached in the memory of the computer.
