Response response1 = request1.Send();
// Find the first form in the response, and store it in a variable
Form loginForm = response1.ExtractForm(0);

...

// Create a POST request that will send the modified loginForm back to the server
Request request2 = WebBrowser.CreateRequest(HttpMethod.POST, url2, 2);

// Fill in the form by specifying a username/password 
loginForm.GetInputElement("username").Value = "Bob Jones";
loginForm.GetInputElement("password").Value = "Pa55word";

// Attach the form to the request and send it to the server
request2.SetMessageBody(loginForm);
Response response2 = request2.Send();

Response response1 = request1.Send();
// Find the first form in the response, and store it in a variable
Form loginForm = response1.ExtractForm(0);

// Create a POST request that will send the modified loginForm back to the server
Request request2 = WebBrowser.CreateRequest(HttpMethod.POST, url2, 2);
