Neat. This is much better that relying on Javascript and the user's 
settings for it. Alternatively you could say:

<dtml-call "RESPONSE.setCookie('cookiesAllowed', 'yes', 
path='your-protected-path', domain='your-server')">
<dtml-call "RESPONSE.redirect('whichever-URL-you-want-to-end-up-at', 
status=302)">

The only advantage of this over the original suggestion is that some 
(probably ancient) browsers may not support and correctly interpret the 
META HTTP-EQUIV whereas the HTTP 302 redirect response is unlikely to fail 
on any browser.
