I found some time ago this little external method posted by Daryl Tester:

=========================================================== def removeRequest(REQUEST, item): "Remove an item from a REQUEST.form" try: del REQUEST.form[item] except: pass return None ===========================================================

This obviously did not work straight away for this particular item, since it was in the cookies section of REQUEST

Yes, that method should rather look like this: def delRequestVar(self, req, name): # No errors of any sort may propagate, and we don't care *what* # they are, even to log them. try: del req.other[name] except: pass try: del req.form[name] except: pass try: del req.cookies[name] except: pass try: del req.environ[name] except: pass That is how CookieCrumbler defines it.

This initially appears to work fine. I call the external method from within a page, and then view REQUEST while still on the same page, and theClient has disappeared. However, if I subsequently go to any other page it is still there.

That's because the cookie is sent with each request by the client. Deleteing it from the request will only delete it from THAT request.

I have tried RESPONSE.expireCookie(item) in the external method, and Zope didn't seem to appreciate that!

\\Zope\\lib\\python\\ZPublisher\\HTTPRequest.py", line 1194, in __getattr__\n raise AttributeError, key\n', 'AttributeError: expireCookie\n'

Looks like you did REQUEST.expireCookie() instead.
