      org.glassfish.grizzly.http.server.HttpHandlerChain

All Implemented Interfaces:

JmxEventListener

public class HttpHandlerChain
extends HttpHandler
implements JmxEventListener

The HttpHandlerChain class allows the invocation of multiple HttpHandlers every time a new HTTP request is ready to be handled. Requests are mapped to their associated HttpHandler at runtime using the mapping information configured when invoking the (org.glassfish.grizzly.http.server.HttpHandler, java.lang.String[])
