I've seen this too. It's when the person creating the web page has tried to stop you saving. In essence, he/she is redirecting the request through a cgi program (look for "cgi" in the url).

Looks like an HTML page with an embedded object (Quicktime or whatever) to play the midi.

Get the HTML page up, do a view source. Dig through the source to find the call to the object. That should have the real address of the midi file "hidden" within it. Cut and paste that address into the browser and all should be well.
