Doesn't the website have to handle that anyways? I mean, I assume that all
the browsers are going to allow users some way to "manage" this stuff, much
like cache/cookies - e.g. you have to assume that at some point in time the
user is going to blow you away. (Especially on mobile devices where space is
more of a premium...)
