Config IIS for serving static files / CDN?

Is there anyway to config IIS to serve static file like CDN? Like Gzip, Cache, E-tag, Mod-date?

And how should we config to make it very robust on massive requests?

I know it's a short question but that's all I want to ask.

To the question on the IIS version, i prefer 6 and 7 IIS. You can give your answer on either 6 or 7 :)

Thanks! I hope people find this question useful!
