Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    byte[] b = new byte[1];
    Properties systemSettings = System.getProperties();
    systemSettings.put("http.proxyHost", "proxy.mydomain.local");
    systemSettings.put("http.proxyPort", "80");

    URL u = new URL("http://www.google.com");
    HttpURLConnection con = (HttpURLConnection) u.openConnection();
    BASE64Encoder encoder = new BASE64Encoder();
    String encodedUserPwd = encoder.encode("mydomain\\MYUSER:MYPASSWORD".getBytes());
    con.setRequestProperty("Proxy-Authorization", "Basic " + encodedUserPwd);
    DataInputStream di = new DataInputStream(con.getInputStream());
    while (-1 != di.read(b, 0, 1)) {
        System.out.print(new String(b));
    }/*from   ww  w .  ja  v  a  2 s . c o  m*/
