in reply to reading and writing a CGI cookie in the same page

can't you create and read a cookie in the same pageview?

Not without some javascript trickery, or a redirect to yourself.

    Forget javascript trickery (as a "helper" javascript rocks, but you can't rely on it so don't rely on it from the beginning).

    It is best to do a redirect (some might call it standard practice). See merlyns article on Basic Cookie Management.

    Basic strategy is

    • user visits foo.cgi
    • you try to set a cookie whilst redirecting to foo.cgi?redirect=1
    • if you can read cookie, do your thing, if not, user don't support cookies, so don't redirect again (redirect=1 to prevent an infinite loop)
