You don't want a "cookies domain", you want a cookie**less** domain. — thejh, Dec 19 '10 at 19:20

There are two ways to accomplish this. You could set the cookie for FQDN (fully-qualified domain name) of www.abc.com, but this would restrict the cookies to just www.abc.com. This may be stricter than you want.

The more common solution it to register a completely separate domain for cookieless hosting. This is used by many websites already.

Google uses gstatic.com
Facebook uses twimg.com (I think)
Yahoo uses yimg.com (I think)
EBay uses ebaystatic.com
etc.

When you create a cookie, set it's Domain property to ".abc.com", that way the cookie will be shared by both the www.abc.com and static.abc.com subdomains.

i don't want to cookie shared with other or static domain. – AjmeraInfo Dec 19 '10 at 19:36
@AjmeraInfo: Then I misunderstood the question. If you don't want to share the cookies then you simply avoid setting the `Domain` property. – Guffa Dec 19 '10 at 23:29
