Emulate & Intercept a Form POST from a Servlet - BONUS AVAIL

Listening...

Let me give you the code I'm using now, maybe that will help, btw: it has to work with https.

    URL url = new URL(scriptURL);
    URLConnection connection = url.openConnection();
    connection.setDoOutput(true);
    String username = "theuser";
    String password = "thepass";
    String moddate = "0000000000000000";
    String redirect = "http://www.url.com/intranet/home.nsf/frNewHome";
    PrintWriter out = new PrintWriter(  connection.getOutputStream());
    out.println( "?Login=" + URLEncoder.encode("true") + "%%ModDate=" + URLEncoder.encode(moddate) + "RedirectTo=" + URLEncoder.encode(redirect) + "&acctid=" + URLEncoder.encode(username) + "&passwd=" + URLEncoder.encode(password));
     out.close();
     BufferedReader in = new BufferedReader( new InputStreamReader(  connection.getInputStream()));
    String inputLine;
     while ((inputLine = in.readLine()) != null)
        output.println(inputLine);
     in.close();

Output is just a printwriter that rights to the response stream, ie: PrintWriter output = response.getWriter();

Now when I set the url to an asp page it lists these values into a list when I do an iteration over all of the elements in Request.Form, so to me it appears it works, but when I tested it against a different url I got basically a failed login, or just a re-write of the page when I printed it. I need to be sure that the above code is:

A:) doing a form POST
B:) is properly encoding the elements
C:) (optional-good bonus for this); how to detect when a redirect is sent, as when I pointed it to a page that checks the credentials, then redirected, java throws a FileNotFoundException I believe.
D:) set a timeout incase the remote server does not respond in a timely fashion, say 3 seconds.

If you know of a better (but fairly lightweight, as this has to be quick) way, then that would also be great.

Thanks

Sorry. That's setRequestMethod ("POST"). Its a member of HttpURLConnection, so you'll have to cast your URLConnection...

If i could curse you out I would, you are the man! I'll post the final piece of code that worked in case anyone else would like to view it in the future, thanks a lot.

    try {
    String scriptURL = "http://url";
    URL url = new URL(scriptURL);
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    String username = "user";
    String password = "pass";
    PrintWriter out = new PrintWriter(  connection.getOutputStream());
    out.println("Username=" + URLEncoder.encode(username) + "&Password=" + URLEncoder.encode(password));
     out.close();
     BufferedReader in = new BufferedReader( new InputStreamReader(  connection.getInputStream()));
    String inputLine;
     while ((inputLine = in.readLine()) != null)
        output.println(inputLine);
     in.close();
     } catch (Exception e) {
      output.print(e.toString());
     }

Here's the relevant comment below:

final code:
    try {
    String scriptURL = "http://url.com";
    URL url = new URL(scriptURL);
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    String username = "user";
    String password = "pass";
    PrintWriter out = new PrintWriter(  connection.getOutputStream());
    out.println("Username=" + URLEncoder.encode(username) + "&Password=" + URLEncoder.encode(password));
     out.close();
     BufferedReader in = new BufferedReader( new InputStreamReader(  connection.getInputStream()));
    String inputLine;
     while ((inputLine = in.readLine()) != null)
        output.println(inputLine);
     in.close();
     } catch (Exception e) {
      output.print(e.toString());
     }

Glad I could help.
