Moshe Elisha created HTTPCLIENT-1242:
----------------------------------------
Summary: Preemptive authentication using AuthCache stopped working
Key: HTTPCLIENT-1242
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1242
Project: HttpComponents HttpClient
Issue Type: Bug
Affects Versions: 4.2.1, 4.2 Final
Environment: JDK 1.6
Reporter: Moshe Elisha
Running the following example with httpclient and httpcore 4.1.1 works fine.
When using httpclient 4.2.1 + httpcore 4.2.2 or httpclient 4.2 + httpcore 4.2,
I get "401 Unauthorized".
The test source code

DefaultHttpClient httpclient = new DefaultHttpClient();
try {
httpclient.getCredentialsProvider().setCredentials(
new AuthScope(targetHost.getHostName(),
targetHost.getPort()),
new UsernamePasswordCredentials("username", "password"));
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local
// auth cache
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
// Add AuthCache to the execution context
BasicHttpContext localcontext = new BasicHttpContext();
localcontext.setAttribute(ClientContext.AUTH_CACHE, authCache);
HttpGet httpget = new HttpGet("/vendor/apps/");
System.out.println("executing request: " +
httpget.getRequestLine());
System.out.println("to target: " + targetHost);
HttpResponse response = httpclient.execute(targetHost, httpget,
localcontext);
HttpEntity entity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (entity != null) {
System.out.println("Response content length: " +
entity.getContentLength());
}
EntityUtils.consume(entity);
} finally {
// When HttpClient instance is no longer needed,
// shut down the connection manager to ensure
// immediate deallocation of all system resources
httpclient.getConnectionManager().shutdown();
}
}
}
