Why does the SimpleHTTPServer not serve wav files when serving a node.js app?

Question

When I do a

http://localhost:8090/

Most of the files in the root directory are displayed: eg .js and .py . But all of the .wav files are omitted. When trying to access it directly:

localhost:8090/mywav.wav

a 404 is returned. Is there some configuration causing this?

Answer 1

Apparently this has to do with node.js . On a hunch I re-ran

 npm init

Now the wav files - which I had added recently after the initial npm init do show up. So.. does that mean that node is whitelisting files - presumably for security purposes? I still do wonder then if there were a way to disable that given this is a localhost server accessed by me myself and I.
