WebClient - Am I logging in right, or being redirected right?

Hi
I'm trying to figure out a way to log into a new site that a 3rd party vendor has provided us by using a script.
I'm new to web related coding.

Its a ticketing site. We have to log into it.
If you attempt to load up a URL directly to a ticket, you are redirected to the login window. Once you log on, you can then view the ticket.

Code:

---

        private void Form1_Load(object sender, EventArgs e)
        {
            string postData = "userName=Removed&password=Removed";
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("End URL's location");
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = postData.Length;
            request.Method = "POST";
            request.AllowAutoRedirect = false;

            Stream requestStream = request.GetRequestStream();
            byte[] postBytes = Encoding.ASCII.GetBytes(postData);
            requestStream.Write(postBytes, 0, postBytes.Length);
            requestStream.Close();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            Console.WriteLine(new StreamReader(response.GetResponseStream()).ReadToEnd());
            Console.WriteLine("Headers:");
            Console.WriteLine(response.Headers.ToString());

            string url = "End URL's location";
            System.Diagnostics.Process.Start(url);
        }

The info that I keep downloading is the login's page html code. Not the ticket page's code.
Console's results (made it a bit easier to read):

<input type="hidden" name="redirectAction" value="Removed_request_dashboard">
<input type="hidden" name="userName" value="Removed">
<input type="hidden" name="inc_id" value="5045176">
<input type="hidden" name="password" value="Removed">


There must be a tiny bit of code I'm missing. The login info is there, but its not logging me in. Or perhaps its logging me in but not directing me properly afterwards.

update...

The 'request' statements are now the following:

request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postData.Length;
request.Method = "POST";
request.AllowAutoRedirect = true;
request.PreAuthenticate = true;
request.Credentials = System.Net.CredentialCache.DefaultCredentials;

The page loads up and has the username & password filled out in the login page.
How do you actually 'submit' it?


The end result is that I don't intend to actually open up the browsers to get the tickets. I plan on downloading the html code which contains the ticket info and parse it.

string postData = "userName=Removed&password=Removed\r";
that worked...

I can directly log into a ticket now.
Still can't get the html code from it yet.

Well I don't know if this will work, as I don't know how the site stores login sessions, therefore this may not think your logged in.

Code:

---

private void Form1_Load(object sender, EventArgs e)
        {
            GetUrl("http://www.website.com/yourloginstring");
        }

        private void GetUrl(string url)
        {
            System.Net.WebClient Client = new System.Net.WebClient();
            string storeHtml = Client.DownloadString(url);
            }
