Answer 1

文档域应该是小写的，规则是这样的:

// Actual domain is "www.foo.com" 
document.domain = "foo.com"; // this is valid 

// Actual domain is "bar.foo.com" 
document.domain = "www.foo.com"; // this is invalid, "bar.foo.com" is not a subdomain of "www.foo.com" 

// Actual domain is "blah.bar.foo.com" 
document.domain = "bar.foo.com" // Ok 
document.domain = "foo.com" // Still ok 
document.domain = "bar.foo.com" // Invalid, you can't change it back to a more specific domain.
