The Javascript can only load the flash by URL. There must be a
filename for them, but it might not be *.swf.

This decision that WWWOFFLE makes on whether to get a URL or not is
made based only on the URL, not based on the information that comes
back from the server. It would be possible to use the mime-type for
blocking, but it is complicated because you would need to make the
request and get the header back before deciding if you want to keep
the file. For very short files you might get all of the file back
before you decide that you don't want it. You cannot ask the server
to send the HTTP headers and then wait for confirmation before sending
the body.
