EarlyHintsAsyncExec

java.lang.Object
- org.apache.hc.client5.http.impl.async.EarlyHintsAsyncExec

All Implemented Interfaces:

AsyncExecChainHandler
```
public final class EarlyHintsAsyncExec
extends java.lang.Object
implements AsyncExecChainHandler
```
Execution chain handler that delivers 103 Early Hints informational responses to a user-provided EarlyHintsListener without affecting processing of the final (non-1xx) response.
This handler forwards each 103 informational response to the listener. All other responses (including the final response) are delegated unchanged.

For security and interoperability, applications typically act only on headers considered safe in Early Hints (for example, Link with rel=preload or rel=preconnect).

Since:

5.6
