Sorry if this is a really stupid question, but either way I'd realy appreciate some help! I have a problem deleting a value "theClient" from REQUEST. The value is set initially using: <dtml-call expr="RESPONSE.setCookie('theClient',whatever_value)"> 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, so I changed it to del REQUEST.cookies[item]. (Please bear with any ignorance I may have displayed here). 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. I have tried RESPONSE.expireCookie(item) in the external method, and Zope didn't seem to appreciate that! What am I doing wrong? TIA Ashley
