Hi, I am having problems to make authentication with Microsoft Proxy server because it requires a domain to authentication. I wrote the following program of test to try the authentication because I did not obtain access servlets. I only receive code 407, of required authentication. I would like know if somebody can help to decide this problem, mainly when is necessary a domain to carry through the authentication. Thanks in advance import java.net.*; import java.io.*; public class TesteProxyAuth { public static void main(String[] args) { try { System.setProperty("http.proxySet", "true"); System.setProperty("http.proxyType", "4"); System.setProperty("http.proxyHost", "my_proxy_ip"); System.setProperty("http.proxyPort", "my_proxy_port"); URL myURL = new URL("http://www.altavista.com"); HttpURLConnection connection = (HttpURLConnection) myURL.openConnection(); String password = "my_domain\\my_user:my_password"; String encodedPassword = URLEncoder.encode( password ); String auth = "Basic " + new sun.misc.BASE64Encoder ().encode (password.getBytes()); connection.setRequestProperty( "Proxy-Authorization", auth); connection.connect(); System.out.println("Response Code = "+connection.getResponseCode()); System.out.println("foi"); } catch(Exception e) { e.printStackTrace(); } } } __________________________________________________ Do You Yahoo!?
