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://iAmNotExisting.com/dummy.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 a threaddump from the hanging thread:

* 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.
