[Zope] Cookies and dictionaries

Hello, I am trying to store a dictionary in a cookie which I would like to retrieve later and use. A test python script is as follows: ########## request = container.REQUEST response = request.RESPONSE dic = {'filter':'yes'} response.setCookie('myCookie', dic) if request.has_key('myCookie'): mydic = request.myCookie print mydic['filter'] return printed ########### When the script is run I get an error:

*Error Type: TypeError* *Error Value: sequence index must be integer*

It seems that the dictionary is returned as a string. How can I cast this string to a dictionary type? Thanks. Kashif
