RE: Cross Site Cooking

    Problem #1 - trouble with these pesky foreigners
    ------------------------------------------------

    Both MSIE and Firefox seem to be perfectly happy with two-period
    ccTLDs domain cookies (.xxx.xx).

    In other words, one can set a cookie for *.com.pl or *.com.fr, and
    override or corrupt credentials or other parameters on hundreds of
    thousands e-commerce websites in that country. It will be also
    possible to plant attacker's session ID on visitor's computer,
    and effectively, steal his credentials when he decides to sign in
    on the target site.

I'm afraid this doesn't work for me.
 
I tried setting a cookie for .com.pl, and
I failed (that is, the browser did not respect
it). If you set a cookie for .kom.pl, it will be OK
(if you're in .kom.pl domain, that is).

The browsers (at least
IE 6.0) seem to be smarter, and use a more fine
grained strategy, e.g. something like:
