WebLogic Server 8.1 API Reference

## weblogic.security.net
Interface ConnectionFilter

All Known Subinterfaces:
  ConnectionFilterRulesListener

All Known Implementing Classes:
  ConnectionFilterImpl

public interface ConnectionFilter
extends java.util.EventListener

Connection filter interface. The server uses this interface to determine whether incoming connections from clients should be allowed.

To program the server to perform connection filtering, set the `weblogic.security.net.connectionFilter` property to the name of a class that implements this interface. The class that implements this interface must have a public no-arg constructor.

The connection filter is not called immediately when a client connects to the server. Rather, 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 send enough bytes to determine the client's protocol.
