Well, that is not really possible due to the nature of
cookies.  Since they are set in your browser and need
to be set before they are sent, it takes one page load
to set it, and one page load to send it.

This having been said, there are certainly
hacks/workarounds that might satisfy your needs:  page
redirects, javascript hacks...

Perhaps the easiest thing to do is to simply check for
REQUEST variables in your test instead of cookies
specifically (use the ! instead of @).  This way on
the first page load (the one that sets the cookie),
you will trigger the test with the the GET value, and
on subsequent loads with the cookie value.  i.e.:

 (:if equal {$!sectionborders} 1:)
 border: yes
 (:else:)
 border: no
 (:ifend:)
