For a request

  % netc chapters.ca 80
  GET / HTTP/1.1
  Connection: close
  Host: chapters.ca
  User-Agent: W3C_Validator/1.305.2.148 libwww-perl/5.800

The host does not respond at all, if you change the User-Agent header,

  % netc chapters.ca 80
  GET / HTTP/1.1
  Connection: close
  Host: chapters.ca
  User-Agent: Mozilla/5.0 (compatible; MSIE 6.0; Windows NT;)

  HTTP/1.1 302 Object moved
  Server: Microsoft-IIS/5.0

It works. For http://www.chapters.indigo.ca/Default.asp I am unable to
reproduce the problem (except with the validator.w3.org installation),
it is possible that the host is explicitly configured to not respond to
validator.w3.org or that there is a bug in one of the network libraries
on validator.w3.org. It works with other validator installations and
other services such as

  http://www.htmlhelp.com/cgi-bin/validate.cgi?url=http://www.chapters.indigo.ca/Default.asp

So I can't tell what the problem might be.
