This makes a new cookie but it doesn't have any data in it - you have to 
get the data from the environment and put it in the cookie. Try this:
     if os.environ.has_key('HTTP_COOKIE'):
          thiscookie.load(os.environ['HTTP_COOKIE'])

Most likely you get an error here; actually a SyntaxError because of the 
extra . after C.

If you show us the tracebacks we can give more specific help.
