title: getting past a scrapy login
body: <p>I'm new to scrapy and having trouble getting past a login page:</p>
  <pre><code>allowed_domains = ['brp.secure.force.com']
  start_urls = ['https://brp.secure.force.com/Login']
  
  formdata = {'j_id0:j_id5:Login1_Dealer_No' : 'XXXXXX', 'j_id0:j_id5:Login1_UserName' : 'XXXXXX', 'j_id0:j_id5:Login1_Password' : 'XXXXXX'},
  </code></pre>
  <p>Login appears to fail as my response is the login page.
  I'm thinking I must have incorrect parameter names. How does one work on this type of issue?</p>
  <p>Thanks,</p>
  <p>Jim</p>
