There are basically 4 ways of requesting headers:
    1) ARTICLE -- all headers + body, supported by everyone
    2) HEAD    -- all headers, supported by everyone
    3) XOVER   -- overview headers, practically speaking, supported by
                  everyone (i.e. don't about it)
    4) XHDR    -- individual headers, not supported by everyone (worry)
    5) XPAT    -- individual headers, where contents match patter, not
                  supported by everyone (worry)
