Now that I think of it a little bit more I'm not so sure what's the
right way to handle this.  A proper reply (from the server to the
client) to a HEAD request will include the correct Content-Length
header.  However, in mod_lisp the Content-Length header sent by the
Lisp process is used to indicate to Apache if Lisp wants to send a
body, i.e. there seems to be no way for the Lisp side to handle HEAD
request in such a way that the content isn't generated but the browser
gets the correct Content-Length header anyway.

Or am I missing something?

Cheers,
Edi.
