How to write and read array from cookies ?

The easiest way to write an array in cookie is serialize it using pickle module and quote returned string with urllib module. For example:

import pickle, urllib
cookie = []
response.set_cookie('some_cookie', urllib.quote(pickle.dumps(cookie)))

And getting an array from cookie:

cookie = pickle.loads(str(urllib.unquote(request.cookies['some_cookie'])))
