Yep, you can do it. Cookies require a very specific expiration time format: '%a, %d-%b-%Y %H:%M:%S GMT' So, to set the expiration to one week in the future, you can use something like (untested): <dtml-call "REQUEST.set('expires', ZopeTime() + 7)"> <dtml-call "RESPONSE.setCookie('mycookie', 'myvalue', expires=expires.strftime('%a, %d-%b-%Y %H:%M:%S GMT'))"> Kevin -----Original Message----- From: Chui Tey <teyc@bigfoot.com> To: zope@zope.org <zope@zope.org> Date: Tuesday, November 02, 1999 4:26 AM Subject: [Zope] Cookies Hi everyone, I must be dense. I have tried and failed to make cookies persist beyond the current browser session. Is this option available? Thanks in advance. Chui
