Package org.eclipse.jetty.server

Class ConnectionLimit

java.lang.Object

org.eclipse.jetty.util.component.AbstractLifeCycle

org.eclipse.jetty.server.ConnectionLimit

All Implemented Interfaces:

EventListener, Connection.Listener, SelectorManager.AcceptListener, LifeCycle

@ManagedObject
@Deprecated(since="2021-05-27")
public class ConnectionLimit
extends AbstractLifeCycle
implements Connection.Listener, SelectorManager.AcceptListener

Deprecated.

The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.

A 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 by adding it via Container.addBean(Object)

Usage:

    Server server = new Server();
    server.addBean(new ConnectionLimit(5000,server));
    ...
    server.start();
