             Summary: Request loses authorization header when redirected by 
proxy
                 Key: HTTPCLIENT-1442
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1442
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.3.1
            Reporter: Tobias Wörenkämper


While being routed through a proxy the (2nd) request loses the authentication 
header and hence I am getting a 401 by the target server. In my case the target 
server does not challenge the authentication which may be the reason (see logs).

I configured my HTTP client like this:
{code}
HttpHost proxy = new HttpHost("proxyhost", Integer.parseInt(####));
AuthScope authScope = new AuthScope(proxy);
BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
Credentials credentials = new UsernamePasswordCredentials("username", "****");
credentialsProvider.setCredentials(authScope, credentials);

RequestConfig requestConfig = RequestConfig.custom()
    .setConnectTimeout(4000)
    .setProxyPreferredAuthSchemes(Arrays.asList(AuthSchemes.BASIC))
    .setTargetPreferredAuthSchemes(Arrays.asList(AuthSchemes.BASIC))
    .build();

HttpClient client = HttpClients.custom()
    .setDefaultRequestConfig(requestConfig)
    .setProxy(proxy)
    .setDefaultCredentialsProvider(credentialsProvider)
    .setTargetAuthenticationStrategy(new SummonAuthenticationStrategy())
    .build();
{code}
        
Then I am sending an HTTP request with an Authorization (Authentication) header 
since the request target needs basic authentication as well:
{code}
    HttpGet getRequest = new HttpGet(“target url”);
    getRequest.addHeader("Authorization", "…..”);
{code}
