[jira] [Updated] (HTTPCLIENT-1892) Request hangs forever although sockettimeout and connecttimeout are set

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Christian F updated HTTPCLIENT-1892:
------------------------------------
    Description: 
I try to perform a head request with the http client. The client uses a proxy. The requested domain is not existing. But the proxy does not close the connection.
But what I dont understand, is why the client hangs forever and non of the configured timeouts activates and aborts the request.
Her is my example code:

{noformat}
httpResponse = proxiedHttpClient.execute(
        new HttpHead("https://static.blogwalk.de/wp-content/uploads/sites/22/2017/08/22104117/166A9899-1.jpg"))
{noformat}


Here is my code for configuring the client:
{noformat}
final String hostName = "proxyhost";
final int port = 1234;
final HttpClientBuilder clientBuilder = HttpClientBuilder.create();
clientBuilder.useSystemProperties();
    clientBuilder.setDefaultRequestConfig(RequestConfig.custom().setCookieSpec(STANDARD).build());
clientBuilder.setProxy(new HttpHost(hostName, port));
clientBuilder.setDefaultCredentialsProvider(
getCredentialsProvider(hostName, port, "proxyuser", proxypassword));
clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());
return clientBuilder.build();
{noformat}

Here is the request performed with curl:
{noformat}
curl -X HEAD --proxy "proxyuser:proxypassword@proxyhost:1234"  "https://iAmNotExisting.com/dummy.jpg" --verbose
* About to connect() to proxy proxyhost port (#0)
*   Trying 15.112.12.32...
* Connected to proxyhost (15.112.12.32) port 1234 (#0)
* Establish HTTP proxy tunnel to iAmNotExisting.com:443
* Proxy auth using Basic with user 'proxyuser'
> CONNECT iAmNotExisting.com:443 HTTP/1.1
> Host: iAmNotExisting.com:443
> Proxy-Authorization: Basic blablub=
> User-Agent: curl/7.29.0
> Proxy-Connection: Keep-Alive
> 
* Operation timed out after 300314 milliseconds with 0 out of 0 bytes received
* Closing connection 0
curl: (28) Operation timed out after 300314 milliseconds with 0 out of 0 bytes received
{noformat}

I think, this is either a bug, because the socket timeout does not work or that a request timeout would be needed if the socket timeout is not intended for this use case

The behavior of the proxy could be caused, because it is a keep-alive session.
