How can java applet be used to mask divx source (with example)?

Question

For example look at ninjavideo's divx player source. It is this:

src="http://127.0.0.1:64651/nv/47244"

How do they use the java applet to output the src as a divx readable file?

It's not "masked" it's just running as a local HTTP proxy. It downloads the file from a HttpURLConnection and listens locally for connections and serves up the video.
