[Zope] cookies

[Andreas Hölzl]

maybe this could be a hint to the solution of your problem:

if you have problems with the "visibility" of your cookies use:
setCookie(..., path='/', ...)

in general cookies are set via the "set-cookie"-tag in the
http-header.
So you allways have to be sure, that a page (maybe dummy-page with
redirect) with a "set-cookie"-header is delivered to the
client-browser bevore referencing to the cookie in the context of
another page.

maybe the API-method "expireCookie" can also be used fruitfully.

some
