rieved HTML page (including
        Content-Length and Content-Type).

        When the method is FTP, a Content-Length header will be
        present if (as is now usual) the server passed back a file
        length in response to the FTP retrieval request. A
        Content-Type header will be present if the MIME type can be
        guessed.

        When the method is local-file, returned headers will include
        a Date representing the file's last-modified time, a
        Content-Length giving file size, and a Content-Type
        containing a guess at the file's type. See also the
        description of the mimetools module.
