Java 17 HttpClient- socket keepalive

Question

Apache's HttpClient provides mechanism to keep the socket alive.

 SocketConfig socketConfig = SocketConfig.custom().setSoKeepAlive(true).build();
 new PoolingHttpClientConnectionManager().setDefaultSocketConfig(socketConfig)

Is there a way to enable TCP keep alive using Java 17 HttpClient?

Why? Isn’t one keepalive mechanism enough? Are you really going to keep these HTTP connections open for two hours? — user207421

How about just adding a keep-alive header to your http request?

for example

HttpRequest request = HttpRequest.newBuilder().uri(URI.create("host"))
.header("Connection", "keep-alive")
.POST(json.body)).build()

Not the same thing, although maybe the OP thinks it is, and anyway it's on by default from HTTP 1.1.
