Class ConnectionLimit

java.lang.Object

org.eclipse.jetty.util.component.AbstractLifeCycle

org.eclipse.jetty.server.ConnectionLimit

All Implemented Interfaces:

Connection.Listener, LifeCycle

@ManagedObject
public class ConnectionLimit
extends AbstractLifeCycle
implements Connection.Listener

A Connection Listener that limits the number of Connections.

This listener applies a limit to the number of connections, which when exceeded results in a call to AbstractConnector.setAccepting(boolean) to prevent further connections being received. It can be applied to an entire server or to a specific connector.
