Yes, there is an HTTP Host header. Yes, responses vary by the *value* but not by the *structure*. As far as Apache is concerned, for instance, I would imagine it's doing a string compare without counting or considering dots. By discussing an arbitrary number of components, that paragraph implies that HTTP cares about the *structure* of the name, when it does not (although some implementations might kludge this with www.domain = domain). And I'll just hasten to add that now between you and Richard there are two interpretations of what the text in the document means. All I am suggesting is a bit of clarity, please. Eliot
