Oracle iPlanet Web Proxy Server 4.0.14 Administration Guide

Setting Cache Behavior for Client Interruptions

If a document is only partially retrieved and the client interrupts the data transfer, the proxy can finish retrieving the document for the purpose of caching it. The proxy’s default is to finish retrieving a document for caching if at least 25 percent of the document has already been retrieved. Otherwise, the proxy terminates the remote server connection and removes the partial file. You can raise or lower the client interruption percentage.
