Oracle iPlanet Web Proxy Server 4.0.14 NSAPI Developer's Guide

sendfile

The sendfile filter method performs a function similar to the writev filter method, but it sends a file directly instead of first copying the contents of the file into a buffer. You do not have to implement the sendfile filter method. If a filter implements the write filter method but not the sendfile filter method, the server will use the write method instead of the sendfile method. A filter should not implement the sendfile method unless it also implements the write method.

Under some circumstances, the server may run slightly faster when filters that implement the write filter method also implement the sendfile filter method.
