This only works in browsers where Javascript is enabled. This is
about the only way to get the button to act as a _real_ back
button.

ANY other method, including fiddling with HTTP_REFERER actually
creates a *forward* link to the previous document. Abigail has written
a very comprehensive document explaining why you can't do this in
HTML, and it applies equally well to imagemaps.
