I do, but not as much as I could.

Their webserver (generically speaking) does know.

Yes, not due to HTTP per se, but due to the server that serves the page.  If
I were google, I'd use the server logs than one reason, which is not really
the point here.

I beg to differ slightly.  When I click a link, the webserver that served
the page is informed of the link that I follow, which I suggested could be
used to re-index the page.  Unless it's a very specific IE/IIS function, I
know from work I did with MCIS that the logs could give you a HTTP 404 error
on the server that served the link, if the browser got a 404 back from that
site.  I may be wrong about this (memory failure?), but we specifically used
that feature to suggest corrections to sites for clients.  I have not
checked whether this is in the HTTP specification, so if may be something M$
did in MCIS/IE at the time.

If I'm completely wrong about this, please shoot quickly and from the hip...
;-)  I promised on won't bleed on your carpet!
