title: Python Requests throwing SSLError
body: <p>I'm working on a simple script that involves CAS, jspring security check, redirection, etc.  I would like to use Kenneth Reitz's python requests because it's a great piece of work!  However, CAS requires getting validated via SSL so I have to get past that step first.  I don't know what Python requests is wanting?  Where is this SSL certificate supposed to reside?</p>
