Examples of org.apache.tomcat.Valve

org.apache.tomcat.Valve
A Valve is a request processing component associated with a particular Container. A series of Valves may be associated with the same Container, creating a request processing pipeline.
HISTORICAL NOTE: The "Valve" name was assigned to this concept because a valve is what you use in a real world pipeline to control and/or modify flows through it. @author Craig R. McClanahan @author Gunnar Rjnning @version $Revision: 1.2 $ $Date: 2000/01/24 08:31:30 $
