title: RestTemplate HttpClient connectionRequestTimeout
body: <p>In order to configure RestTemplate I use the following configuration:</p>
  
  <pre><code>HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(HttpClients.createDefault());
  httpRequestFactory.setConnectTimeout(connectionTimeoutMs);
  httpRequestFactory.setConnectionRequestTimeout(readTimeoutMs);
  httpRequestFactory.setReadTimeout(readTimeoutMs);
  
  RestTemplate restTemplate = new RestTemplate(httpRequestFactory);
  </code></pre>
  
  <p>I understand the purpose of connection and read timeouts. But I don't understand the purpose of connection request timeout. It also not clear from Javadoc what does it mean. Could you please explain it ?</p>
