cookies and domains.

[rube]

i'm building a site with a secure login page. cookies are set when login is completed. problem is, the site doesn't have it's own certificate, so i have to use scripts run from the isp's domain to do it. my understanding is that i can't set cookies from a script on one domain to be read by scripts on another, and that scripts from the other domain can't read scripts set by the first domain. is this correct?
is there a solution, short of pressing the site's owner to get their own certificate? can you suggest so on-line reading to help me figure this stuff out?

thanks,
rob.

It's supposed to be true that cookies are not usable cross-domain. But I don't think you need a certificate to set/use cookies.
