If it is returned as a text file to an HTTP request, the server is funny.
Normally a simple reference is treated as a reference to coordinates
0,0 - which should contain the fall back action for non-GUI browsers.

Normally the server is configured to know that things ending in particular
file name extensions should be treated as server side maps, rather than
as files to download.  It looks like your server requires a ? as well,
meaning it does not fall back properly.

The two reasons for using server side maps are to support browsers that
pre-date client side maps and to handle shapes that are too complex for
client side maps.  Ideally every client side map should be backed up by
a server side one.
