CrossOriginOpenerPolicyRequestCycleListener (Wicket Parent 9.18.0-SNAPSHOT API)

java.lang.Object
- org.apache.wicket.coop.CrossOriginOpenerPolicyRequestCycleListener

All Implemented Interfaces:

IRequestCycleListener
```
public class CrossOriginOpenerPolicyRequestCycleListener
extends Object
implements IRequestCycleListener
```
Sets Cross-Origin Opener Policy headers on the responses based on the policy specified by CrossOriginOpenerPolicyConfiguration. The header is not set for the paths that are exempted from COOP.
COOP is a mitigation against cross-origin information leaks and is used to make websites cross-origin isolated. Setting the COOP header allows you to ensure that a top-level window is isolated from other documents by putting them in a different browsing context group, so they cannot directly interact with the top-level window. Using COEP and COOP together allows developers to safely use * powerful features such as SharedArrayBuffer, performance.measureMemory(), * and the JS Self-Profiling API.See CrossOriginEmbedderPolicyRequestCycleListener for instructions * on how to enable COOP.
