session management middleware

This file overrides Beaker's built-in SessionMiddleware
class to automagically use secure cookies over HTTPS.

Original Beaker SessionMiddleware class written by Ben Bangert
"""

from beaker.middleware import SessionMiddleware
from beaker.session import SessionObject


class SecureSessionMiddleware(SessionMiddleware):
    def __call__(self, environ, start_response):
        """
        This function's implementation is taken directly from Beaker,
        with HTTPS detection added. When accessed over HTTPS, force
        setting cookie's secure flag.

        The only difference from that original code is that we switch
        the secure option on and off depending on the URL scheme (first
        two lines). To avoid concurrency issues, we use a local options
        variable.
