How add a cookie to specific domain using selenium

Is there a way to specify the domain in which the cookie is to be set.

I foll开发者_C百科owed this way

selenium.open(example.com); selenium.createCookie(arg1, arg2);

Is there any way by which i can set the cookie in .example.com domain?

Note : If i open example.com it will be redirected to www.example.com
