Regarding the difference between the three Timeouts in Java's HttpClient

When using Apache's HttpClient, I can set the following three timeout values (milliseconds), but I didn't understand the difference well, so I tried to summarize them myself.

import org.apache.http.client.HttpClient;
import org.apache.http.client.config.RequestConfig;

RequestConfig config = RequestConfig.custom()
    .setConnectTimeout(30000)
    .setConnectionRequestTimeout(30000)
    .setSocketTimeout(30000)
    .build();
      
HttpClient httpClient = HttpClients.custom()
    .setDefaultRequestConfig(config)
    .build();

ConnetionTimeout The timeout value for sending a connection request to the server and receiving a response that the connection has been established. In short, set the time allowed for a connection to be established with a 3-way handshake.

ConnectionRequestTimeout The timeout value after the above connection is completed until the request is sent to the server and the response is returned.

SocketTimeut A timeout value used to monitor socket communication. Packets are continuously received in socket communication, but if the reception interval is longer than this value, a timeout (= SocketTimeoutException) occurs.
