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.
