    and in a similar vein the same goes for custom error redirection

    3. does the use of custom errors such as invalid directory (404) etc have a
    miminal impact on server resources or it is significant

    4. ... and are there any easy ways to monitor/measure/compare ?

      Thats not easy to answer because

      1. The question isn't that clear (when a 404 happens the server has to do
      something anyway)
      2. In normal circumstances errors would be rare hence performance impact
      would not be a consideration

      Don't know of 'easy' ways, although your definition of 'easy' may differ
      from mine.

      Putting it all together you are considering sending images using a Custom
      404 hack. Its much more expensive than allowing IIS to serve up the images
      itself.

          I was thinking in terms of having virtually having no directory structure
          to speak of so virtually all requests would be via custom redirection to a
          database or some other routing technology

              Funny that I've just this minute been discussing that in the iis group (see
              subject ' custom 404 page headers problem' started by 'Simon')

              Also in this group 'Detecting if modified since in Classic Asp' started by
              'Simon'

              However I don't need either of these threads to say: Don't do it, its just
              plain mad.

              At least not in this way (using the 404 hack).

              Instead get yourself a freebie ISAPI URL rewriter and do it that way.
