my ASX files are loading into browser like html file?!

[developer]

Please help.

I've managed to embed a player to play asf files (with asx) but cannot seem
to get a stand-alone browser from a hyperlink. Is there something I'm
missing.

The page in question is
http://rodneysharman.com/listening/sharman-proximityofmars28.htm You'll
hear that the embedded player works great, but i can't get the stand alone
to work.

here is the tag i'm using:
<a HREF="http://rodneysharman.com/listening/sharman-proximity.asx">
Start the stream in the stand-alone player.</a>

my asx file is:
<ASX VERSION="3">
<Title>Rodney Sharman Composer</TITLE>

<ref href="http://rodneysharman.com/listening/sharman-proximity.asf" />
<TITLE>Proximity of Mars</TITLE>
