Search for NTLM.
Looks like you need a NTCredential object.

Hi Ashraf,

I would suggest the following:

client.getState().setProxyCredentials(null, ''192.168.0.200", proxyCredentials);

Dears,

My client machine accesses the Internet through a proxy, I'm writing
http client program to download page source from the Internet, here is
my code:

   HttpClient client = new HttpClient();

HostConfiguration hostConfiguration = client.getHostConfiguration();

   hostConfiguration.setProxy( "192.168.0.200", "8080" );

   HttpState state = client.getState();

   Credentials proxyCredentials = new UsernamePasswordCredentials(
"username", "password" );

   state.setCredentials( "rayasoftware.com", "192.168.0.200",
proxyCredentials );

   PostMethod cnnPost = new PostMethod( "http://www.cnn.com"; );

   cnnPost.setDoAuthentication( true );

   client.executeMethod( cnnPost );

   System.out.println( cnnPost.getStatusLine().toString() );

   // release any connection resources used by the method

   cnnPost.releaseConnection();

I'm getting the following message:

HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires
authorization to fulfill the request. Access to the Web Proxy service is
denied. )

[WARN] HttpMethodBase - -No credentials available for the 'null'
authentication realm at 192.168.0.200

What is wrong with my code.

Thanks, Best regards
