[Fwd: Re: [Zope] Re: CookieCrumbler problem]

I guess noone has experience with my particular problem. I traced through CookieCrumbler.py and found that modifyRequest() is raising CookieCrumblerDisabled. The caller __call()__ then catches this exception and returns silently. Why would my CookieCrumbler be disabled? I even deleted my Crumbler and created a new one and still got the same exception. I do see that sometimes disable_cookie_login__=1 gets appended to my URL when I try to login. Why does this happen? Is this related to my problem, even though I've seen this happen when my system was working properly? Thanks, Gordon
