Missing settings for HttpClient timeouts ?

[Óscar Frías Barranco]

Hello.

I am trying to configure HttpClient to validate a list of URLs and I don't
want it to take longer than 10 seconds for each URL.  I have been searching
for all available timeout settings in HttpClient but, even after setting
them all to 2 seconds, HttpClient still takes longer than 10 seconds for
some URLs.

This is an example test case that configures all known timeouts to 2
seconds but the HttpClient execution takes about 15 seconds:

SocketConfig socketConfig = SocketConfig.copy(SocketConfig.DEFAULT)
        .setSoTimeout(Timeout.ofSeconds(2))
        .build();

ConnectionConfig connectionConfig =
ConnectionConfig.copy(ConnectionConfig.DEFAULT)
        .setConnectTimeout(2, TimeUnit.SECONDS)
        .setSocketTimeout(2, TimeUnit.SECONDS)
        .build();

PoolingHttpClientConnectionManager connManager =
PoolingHttpClientConnectionManagerBuilder.create()
        .setDefaultSocketConfig(socketConfig)
        .setDefaultConnectionConfig(connectionConfig)
        .build();

RequestConfig defaultRequestConfig = RequestConfig.copy(RequestConfig.DEFAULT)
        .setConnectionRequestTimeout(2, TimeUnit.SECONDS)
        .build();

CloseableHttpClient httpClient = HttpClients.custom()
        .setConnectionManager(connManager)
        .setDefaultRequestConfig(defaultRequestConfig)
        .build();

ClassicHttpRequest httpGet = ClassicRequestBuilder
        .head("https://www.anek.gr/en/";)
        .build();

Instant start = Instant.now();
httpClient.execute(httpGet, response -> {
    System.out.println(response.getCode() + " " + response.getReasonPhrase());
    final HttpEntity entity1 = response.getEntity();
    EntityUtils.consume(entity1);
    return null;
});
Instant end = Instant.now();
long diff = ChronoUnit.SECONDS.between(start, end);
System.out.println("It takes " + diff + " seconds.");


Am I missing a timeout setting?  Are there missing knobs in HttpClient
configuration?

Thanks!
