  Index: dict-ap_custom_response.html
  This routine permits modules to provide a custom response body for
  error pages instead of the standard ones provided by the core
  server.  This function has an effect quite similar to that of the
  <code>ErrorDocument</code> directive, except that the API routine
  only supplies a response body for the specified request rather than
  a general one for all responses with the indicated status code, and the
  body is a string, rather than a script or something to be invoked.
