             Summary: HttpClient does not support (non preemptive) digest authentication 
                 Key: HTTPCLIENT-1970
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1970
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient (classic)
    Affects Versions: 4.5.6
            Reporter: Cisto Cyriac


In HttpClient 4.5.6 the preemptive digest authentication works, however non-Preemptive digest authentication does not work.  We found this issue when the HttpClient library was upgraded from 4.4.1 to 4.5.6.  

As per  rfc2617  https://tools.ietf.org/html/rfc2617#section-3.2.1

nonce  is a server-specified data string which should be uniquely generated each time a 401 response is made.

This issue can  be reproduced by commenting out the following two digest authentication override parameters in the preemptive auth example in https://hc.apache.org/httpcomponents-client-4.5.x/httpclient/examples/org/apache/http/examples/client/ClientPreemptiveDigestAuthentication.java

 

DigestScheme digestAuth = new DigestScheme();
// Suppose we already know the realm name
//digestAuth.overrideParamter("realm", "some realm");
// Suppose we already know the expected nonce value
//digestAuth.overrideParamter("nonce", "whatever");
