[Zope] - pcgi, os.environ, and cookies

Hi, I've got bobo application that I've converted to run under the pcgi that comes with Zope 1.9 final. The application uses a cookie based authentication/identification scheme. The problem is that the app runnning under pcgi seems to maintain the environment under which it was started, which means that the cookie info never changes. If I start the app as an authenticated user, anybody can get in; if I start it as a non authenticated user, nobody can get in. I've confirmed the static environ by logging it; it never changes. I'm using an old cookie.py module: # by Dave Mitchell (davem@magnet.com), 1995 Maybe there is another way to get fresh cookies? Thanks Bill
