I see. Funny this hasn't come up before.
I was testing something like this the other day and decided that the way I
was doing it, the info was coming from the client (passing the URL to the
httpd) rather than the URL coming from the server page. It seemed to be
the best explanation for what I was seeing. I was just retrieving a page
that was already there, rather than asking for a gif to be generated first
then retrieved.
All this is speculation and can be revised in the face of more evidence.
Do you find that you can't retrieve the gif sometimes? What if you refresh
n times where n is the number of real-servers, do you eventually get
the gif?

Very interesting
