Hi all, so I tried this with no luck to post login through, still ending up on the login page:
thanks for the help

Java Code:
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.HttpConnection;
import java.net.URLEncoder;
import java.net.URLConnection;
import java.net.URL;
import java.io.*;
import java.io.IOException;

 class ConnectIntellio1 {

  public static void main(String[] args) {

	OutputStreamWriter writer = null;
	BufferedReader reader = null;

	try {

	String encodedData = URLEncoder.encode("UserID","UTF-8");
	URL url = new URL ("http://www.intellio.fr/extranet/index.php");

     URLConnection conn = url.openConnection();
      conn.setDoOutput(true);
	  writer = new OutputStreamWriter(conn.getOutputStream());
      writer.write(encodedData);
      writer.flush();

      reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
      String ligne;
      while ((ligne = reader.readLine()) != null) {
         System.out.println(ligne);
      }


      //InputStream responseBody = conn.getInputStream();

	  //File f=new File("outFile.html");

      /*BufferedOutputStream out=new BufferedOutputStream( new FileOutputStream(
                  f.getName() ) );

    	byte buf[]=new byte[1024];
    	int len;
    	while((len=responseBody.read(buf))>0)
    	out.write(buf,0,len);
    	out.close();
    	responseBody.close();

      System.out.println("Fichier créé");*/


    } catch (Exception e) {

      System.err.println("Fatal protocol violation: " + e.getMessage());
      e.printStackTrace();}

      finally {

      try{writer.close();}catch(Exception e){}
      try{reader.close();}catch(Exception e){}

    }
  }
