  Modified:    htdocs/manual/mod core.html
  Log:
  One more update that Jim forgot for the "config directory" patch.
  Plus, get rid of links to the obsolete and redundant keepalive.html.
  Instead, include the information with the directive.

  +<li>Keep-Alive support must be enabled by setting this directive
  +to <code>On</code>.</li>
  +<li>The client must support Keep-Alive requests.  Most current
