WebLogic Server 5.1.0sp9 API Reference

## weblogic.security.net
Interface ConnectionFilter

All Known Implementing Classes:
  ConnectionFilterImpl

public interface ConnectionFilter
extends java.util.EventListener

Connection filter interface. This interface is used by the server to determine whether it should allow or reject incoming connections from clients.

You can make the server perform connection filtering by setting the `weblogic.security.net.connectionFilter` property to the name of a class that implements this interface. That class must have a public no-arg constructor.

The connection filter is not called immediately when a client connects to the server. It is called after the client has sent enough bytes for the server to determine what protocol the client is using. The login timeout and protocol mechanisms will deal correctly with clients that do not get this far.
