HttpClient Login Cookie/Session Management

[Cadicus]

Hello Developers!

Thank you for taking the time to read this email. Any insight would be greatly appreciated. I am attempting to log into a website automatically using a PostMethod. I'm having trouble getting the cookies / session lined up properly to do so. Below is the code I am working with. Any suggestions / guidance is appreciated!

HttpClient Loginclient = new HttpClient();
PostMethod post = new PostMethod("http://www.throneit.com/forums/ucp.php?mode=login");

NameValuePair[] logindata =
        {
            new NameValuePair("username", "Cadicus"),
            new NameValuePair("password", "###Censored###"),
            new NameValuePair("autologin", "checked"),
            new NameValuePair("login", "Login"),
            new NameValuePair("sid", sessionID)    <--  Do I need to provide this?  If so, How can I pull the session ID from a post?
        };

post.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
post.setQueryString(data);
Loginclient.executeMethod(post);
String htmlCode = post.getResponseBodyAsString();

** Process results **

Thank you in Advance,

Chris
