Subject Re: Proxy with digest authentication
Date Wed, 13 Apr 2016 14:24:45 GMT
Hi,

Thanks Mark for your help, it's now ok with :

new AuthScope(proxy, AuthScope.ANY_REALM, AuthSchemes.DIGEST)



In my mind, the default constructor was with AuthSchemes.ALL and so should
work with DIGEST.
But with the specified DIGEST value, it's ok, thank you very much.
