Question

I would like to fetch a SSL page in Java. The problem is, that I have to authenticate against a http proxy.

So I want a simple way to fetch this page. I tried the Apache Commons httpclient, but it’s too much overhead for my problem.

I tried this piece of code, but it does not contain an authentication action:

import java.io.*; import java.net.*;  public class ProxyTest {    public static void main(String[] args) throws ClientProtocolException, IOException {      URL url = new URL('https://ssl.site');     Socket s = new Socket('proxy.address', 8080);     Proxy proxy = new Proxy(Proxy.Type.HTTP, s.getLocalSocketAddress());      URLConnection connection = url.openConnection(proxy);     InputStream inputStream = connection.getInputStream();     BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));     String tmpLine = '';      while ((tmpLine = br.readLine()) != null) {       System.out.println(tmpLine);     }    } } 

Can anyone provide some information how to implement it on an easy way?

Thanks in advance

org.apache.commons.httpclient.HttpClient is your friend,

Sample code from http://hc.apache.org/httpclient-3.x/sslguide.html

  HttpClient httpclient = new HttpClient();   httpclient.getHostConfiguration().setProxy('myproxyhost', 8080);   httpclient.getState().setProxyCredentials('my-proxy-realm', ' myproxyhost',   new UsernamePasswordCredentials('my-proxy-username', 'my-proxy-password'));   GetMethod httpget = new GetMethod('https://www.verisign.com/');   try {      httpclient.executeMethod(httpget);     System.out.println(httpget.getStatusLine());   } finally {     httpget.releaseConnection();   }
