Currently, only the MS Internet Explorer supports this feature, the client
imagemap. The traditional imagemap resolution is now done on the client
computer. No CGI programs are involved in the process. The whole point
-> URL mapping is actually downloaded to one's browser, as "map4" in the

USEMAP="" is to select the correct map info for a client imagemap.

Actually, MS has put the complete related info on their Web site, I just
can't recall the correct place.
