HttpSessionIdListener (Servlet 5.0 API Documentation - Apache Tomcat 10.0.27)

All Superinterfaces:

java.util.EventListener
```
public interface HttpSessionIdListener
extends java.util.EventListener
```
Implementations of this interface are notified when an HttpSession's ID changes. To receive notification events, the implementation class must be configured in the deployment descriptor for the web application, annotated with WebListener or registered by calling an addListener method on the ServletContext.

Since:

Servlet 3.1
