Sun Java System Web Server 7.0 Update 3 NSAPI Developer's Guide

NSAPI Filter Interface

The NSAPI filter interface complements the NSAPI Server Application Function (SAF) interface. Filters enable functions to intercept and possibly modify data sent to and from the server. The server communicates with a filter by calling the filter's filter methods. Each filter implements one or more filter methods. A filter method is a C function that performs a specific operation, such as processing data sent by the server.
