no backticks

also, why not return the storeId here as well?

[Mike West, 2011/02/15 14:26:58]

Done.
The storeId is returned as a property of the cookie that's been set.  That's
probably enough.

why would storeId be optional?

[Mike West, 2011/02/15 14:26:58]

Because I thought it would be tough to grab.  As it turns out, it isn't, since
we need it for CookieMonster anyway.  Removing the optional flag.
