Handle secure cookies

[jkoehl]

If a secure cookie is set then webobtoolkit has an issue attempting to send the cookie on subsequent requests.

The issue appears to be with the cookie filter not creating a proper mock request with a get_type() function so cookielib can verify the scheme used to send the request.

It blows up here in cookielib.py:

    def return_ok_secure(self, cookie, request):
        if cookie.secure and request.get_type() != "https":
            _debug("   secure cookie with non-secure request")
            return False
        return True

But the root cause is this class in filters.py just needs to implement this get_type() function...

class RequestCookieAdapter(object):
    """
    this class merely provides the methods required for a
    cookielib.CookieJar to work on a webob.Request

    potential for yak shaving...very high
    """
    def __init__(self, request):
        self._request = request

    def is_unverifiable(self):
        return True  # sure? Why not?

    def get_full_url(self):
        return self._request.url

    def get_origin_req_host(self):
        return self._request.host

    def add_unredirected_header(self, key, header):
        self._request.headers[key] = header

    def has_header(self, key):
        return key in self._request.headers
