	The httpd server 2.0 and above and all browsers using the www
	library 2.0 and above support this feature.  The server
	at CERN for example supports it.  If you run the www
	line mode brwser even with DISPLAY set to point to an
	X display it will launch ghostview or xv.  So will (I
	suppose) tkWWW for example.  XMosaic doesn't do it but will
	one day, when a lot of confusion will cease.
	On the server side, in the current implementation, the
	dummy suffix ".multi" means "Whatever file of this name
	and any suffix which I can handle and you think best".
	There are a few examples in the test file
