Step 6 of Add Cookie spec unclear

[julianrkung]

In chapter 14. Cookies, section 14.3 Add Cookie:

cookie domain is not equal to the current browsing context’s active document’s domain

It is unclear whether this "not equal" should be interpreted literally, or if this is meant to be a set-like equivalence.

For example, if the user was currently on the site "foo.bar.com", the current spec (if taken literally) would not allow the user to set a cookie for "bar.com", which he/she should be allowed to do. A clarification or rewording would be much appreciated.

The tests for Add Cookie are not crystal clear on whether the behaviour you desire is actually what WebDriver is meant to do… it would be good if they were updated to test the various permutations for cross-site origins, subdomains, and “leading-dot” domain cookies.

Since .example.com is meant to work for example.com, plus its subdomains such as www.example.com, the wording in the spec is quite misleading. From my last read, the RFC on cookies isn’t much better, but there may be some terminology there we can borrow instead of “not equal to”?
