[Zope] How to expire cookie in DTML? Solved!

[Philip Aylesworth]

This is an interesting conversation that I am having with myself. For
the record I thought I would post what I have found.

By searching through the UserDB code I found that the author expires the
cookie with path='/' so I tried that. It worked! So if anyone wants to
use UserDB with cookies they can log out users by having a DTML method
like this:


<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<P> You are now logged off.</P>
<!--#call "RESPONSE.expireCookie('__ac', path='/')" -->
<!--#var standard_html_footer-->


It works with both Netscape and MSIE.
