Unfortunately, that won't work. Most handlers have a clause that looks like
this:

db_req(#httpd{path_parts=[_DbName]}=Req, _Db) ->
    send_method_not_allowed(Req, "DELETE,GET,HEAD,POST");

that will catch that inappropriate HEAD request. I guess
send_method_not_allowed/2 could be modified to test if HEAD is in the list
and throw an error.

I'll dig into the archives and see if I can find the previous discussion on
the topic. I might have to put an uber-ugly hack in for my use in the
meantime. I don't mind spending time doing the "right" thing as long as I
know what the "right" thing is.
