Deprecated, for removal: This API element is subject to removal in a future version.

use NetworkConnectionLimit instead

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. This listener can be applied to an entire Server or to a specific Connector by adding it via Container.addBean(Object).

When the number of connections is exceeded, the idle timeout of existing connections is changed with the value configured in this listener (typically a shorter value).

Usage:

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

Constructor Details

ConnectionLimit

public ConnectionLimit(@Name("maxConnections")
 int maxConnections,
 @Name("server")
 Server server)

Deprecated, for removal: This API element is subject to removal in a future version.

ConnectionLimit

public ConnectionLimit(@Name("maxConnections")
 int maxConnections,

Method Details

getIdleTimeout

@ManagedAttribute("The endpoint idle timeout in ms to apply when the connection limit is reached")
public long getIdleTimeout()

Deprecated, for removal: This API element is subject to removal in a future version.

Returns:

the endpoint idle timeout in ms to apply when the connection limit is reached

setIdleTimeout

public void setIdleTimeout(long idleTimeout)

Deprecated, for removal: This API element is subject to removal in a future version.

Sets the endpoint idle timeout in ms to apply when the connection limit is reached.
