CGI for USEMAP

The below stuff was taken from a web page at Microsoft.  I don't 
understand the <a href="front-door.map"> beyond the fact that it
sensitizes the image so one can click on it.  Is there CGI code
that sits on their server, and what does it look like?  How
does it use the map4 defined in the HTML file sent to the browser?
Does anybody understand this stuff?  Thanks for your help!

<a href="front-door.map"><img border=0 width=623 height=339 
src="img/front-door.gif" USEMAP="#map4" ISMAP></a>

<map name="map4">
<area shape="rect" coords="116,0,350,115" href="intro1.html">
<area shape="rect" coords="1,113,243,234" href="surfing1.html">
<area shape="rect" coords="350,115,585,231" href="advanced.html">
<area shape="rect" coords="468,233,587,339" href="menu.html">
</map>

A fellow web weenie sent me the above mail message. After talking to him,
I found out that what he really needs is an example. I haven't done this
sort of thing before so I don't even know where to start (other than here).
I don't understand the need for the href to "front_door.map" when there is
already an href to the html files in the map declaration. Thanks alot.
