title: Python - Using Cookies Successfully
body: <p>When I would try facebook cookies to open a logged account on facebook...</p>

  cookie_POST = opener.open(cookie_request)
  
  if "Logout" in cookie_POST.read():
      print("Logged In")
  </code></pre>
  
  <p>It would print "Logged In" the first time successfully, but when I try using the cookie, I would not be logged in. How can I fix this? (Without using other downloaded modules)</p>
