    Interestingly, you can break a lot of websites by adding a trailing dot to the URL, like twitter.com..

    It’s a perfectly valid URL, a fully-qualified one, and should resolve to the same place with or without the trailing dot. Some sites, like google.com. handle it correctly, but many fail completely, or fail partially, or at least don’t preserve your login session.
