This package contains a drop-in replacement middleware for
django.contrib.sessions.middleware.SessionMiddleware to store all session data in
a browser cookie instead of the database. The code is based on a snippet from Christopher Lenz.
To prevent user tampering the session dictionary goes through the following encoding steps:
* The session dictionary is converted into json
* A sha1 hash is made with the json and the site's SECRET_KEY
* The json and sha1 hash are concatenated, gzipped and base64 encoded.

Upon decoding:
* The cookie is base64 decoded and ungzipped
* The data is split into the sha1 hash and the json data
* The sha1 hash is regenerated from the received json data and the site's SECRET_KEY
* If the hashes don't match, a SuspiciousOperation exception is raised. If the hashes match,
the json data is converted into a python object and returned.
