Would a flush bucket be a great way to say "send headers now"?
So if you're not going to send the actual content down the filter chain
on a HEAD request, would sending a flush bucket make things happy?
It does.
IIF this works, can I make a request the $r->send_http_header(

Thanks Glenn, calling $r->rflush works perfectly fine to cause

I just missed the content-length header on HEAD requests that is
delivered on GET.
Geoff, see the t/apache/head_request.t test I've added last night. If
you don't send a body, Apache strips the C-L header for HEAD requests.
Sending at least 1 byte works as a workaround,

that is exactly what I mean - if you include a C-L header on a GET then you
are supposed to have one for a HEAD request as well, expensive or not.

I get indentical behavior with either of the two methods:
my $body = "This is a response string";
#$r->headers_out->{'Content-Length'} = length $body;
$r->set_content_length(length $body);
$r->print('a');

It's somewhat documented:
