Not new to this patch, but the double string comparison makes me a little sad. In the past I've done something like this:

    String netflixDomain = ASCIILiteral("netflix.com");
    if (!host.endsWithIgnoringASCIICase(netflixDomain))
        return true;

    unsigned suffixOffset = host.length() - netflixDomain.length();
    return suffixOffset && host[suffixOffset - 1] != '.';

Does this mean that Now Playing scrubber controls will now be enabled again for Netflix?

Isn't it possible for host.length to be smaller than netflixDomain.length?

We already know that host ends with netflixDomain at this point, so it must be at least as long as netflixDomain.

Cool, I'll try this! Thanks Andy!

It means that Netflix will have all of the controls, but if a user tries to use the timeline to scrub, nothing will happen.
