Using HTTPClient to login to Yahoo Briefcase

[Christopher Valorose <cv...@yahoo.com>]

Hello,

I am attempting to use HTTPClient to login into Yahoo.
No matter what I do I keep getting the Yahoo logon
page again. See code below. Any examples or help is
greatly appreciated.

	public boolean formLoginYahoo( String user, String
password){
		boolean bFormLogin = false;
		String url = "https://login.yahoo.com";
		int port = 443;
		
        _client = new HttpClient();
        _client.getHostConfiguration().setHost(url,
port, "https");
       
_client.getState().setCookiePolicy(CookiePolicy.COMPATIBILITY);
		
		GetMethod authget = new GetMethod(url);

		try{
			_client.executeMethod(authget);
		}
		catch (IOException i){
			i.printStackTrace();
		}
        System.out.println("Login form get: " +
authget.getStatusLine().toString()); 

		// Read the response body.
		byte[] responseBody = authget.getResponseBody();
		_strGetRspBody = authget.getResponseBodyAsString();
		_logger.logDebug("GetRspBody: " + _strGetRspBody);
		
		// release any connection resources used by the
method
        authget.releaseConnection();
		
		//Get the .u value
		int intUStart = _strGetRspBody.indexOf("<input
type=\"hidden\" name=\".u\"");
		intUStart = intUStart + 38;
		String strU = _strGetRspBody.substring(intUStart,
intUStart + 13);
		_logger.logDebug("U value from Get: " + strU);
		
		
		//Get the .challenge value
		int intChallengeStart =
_strGetRspBody.indexOf("<input type=\"hidden\"
name=\".challenge\"");
		intChallengeStart = intChallengeStart + 46;
		String strChallenge =
_strGetRspBody.substring(intChallengeStart,
intChallengeStart + 28);
		_logger.logDebug("Challenge value from Get: " +
strChallenge);

"login");

        NameValuePair username  = new

        NameValuePair passwd	= new

	    // See if we got any cookies
        // The only way of telling whether logon
succeeded is 
        // by finding a session cookie

results in a redicrect to

            if (header != null) {
                String newuri = header.getValue();
