Having problems with Proxy Connections

[Benjamin Pasero <be...@web.de>]

Hi,

I am wondering why some of my users fail to use a proxy server. I am
running my application with HttpClient 3.0 RC1.

In order to make the connection ready for proxy, I am:

1.) Calling HttpClient#getParams().setAuthenticationPreemptive(true);

2.) Calling HttpClient#getHostConfiguration().setProxy(proxyHost,
proxyPort);
    with the Proxy Host and Proxy Port entered by the user.

3.) Then in case a username and password is supplied (and ONLY then)
calling:

    AuthScope proxyAuthScope = new AuthScope(proxyHost, proxyPort);
    UsernamePasswordCredentials proxyUserPasswd = new
UsernamePasswordCredentials(proxyUsername, proxyPassword);
    HttpClient#getState().setProxyCredentials(proxyAuthScope,
proxyUserPasswd);

That is it, or am I missing something here? Should I maybe use
NTCredentials just in case
the Proxy uses NTLM Authentification. Any other Tips?

Regards,
Ben
