 I wish to do that. It will be easy for me because I know how the test
directory is architectured. It will be harder for others. Could you
write a small t_htnet containing a test for this, even if for nothing else ?

 And provide fallback for emulating HEAD with GET for servers that do not
implement HEAD (there are such servers although I could not say which).
Emulating HEAD is easy : GET + trunc the connection after reading header.
