Cool, I'm immortalized in the FAQ : )
Actually, it turns out that it's not quite this easy -- with some JSDK / JSP
engine combos (actually, I'm pretty sure it's the JSDK that matters, but I
can't demonstrate that with certainty), even this method doesn't work when
the client's clock is *behind* the server's clock. The problem is that with
some versions (e.g., WebSphere with 0.91 JSP), setMaxAge(0) sets the expire
time to the time when the call is made. If the client's clock is behind
that, then it thinks the expire time is in the future, and doesn't expire
the cookie.
The only combo I know that works is JRun 2.3 (which uses JSDK 2.1, I
believe).
