Cc'ing wget ML, as it's probably important to open up discussion of the current logic. What about the case when nothing is given on the command line except - --no-content-disposition? What do we need HEAD for then? Also: I don't believe HEAD should be sent if no options are given on the command line. What purpose would that serve? If it's to find a possible Content-Disposition header, we can get that (and more reliably) at GET time (though, I believe we may currently be requiring the file name before we fetch, which if true, should definitely be changed but not for 1.11, in which case the HEAD will be allowed for the time being); and since we're not matching against potential accept/reject lists, we don't really need it. I think it really makes much more sense to enumerate those few cases where we need to issue a HEAD, rather than try to determine all the cases where we don't: if I have to choose a side to err on, I'd rather not send HEAD in a case or two where we needed it, rather than send it in a few where we didn't, as any request-response cycle eats up time. I also believe that the cases where we want a HEAD are/should be fewer than the cases where we don't want them. - -- Micah J.
