Config IIS for serving Static files / CDN?

Question

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!

Answer 1

regardless of the server (IIS, Apache, etc.):

You achieve robustness through scale. Put 1000-2000 servers behind a few hardware load-balancers (F5's). Monitor constantly to ensure they all have the same files. Secure your file system so writes are allowed by only 1-2 users. Spread them geographically across network providers, power suppliers and backhoe opportunities.

Or just outsource it to someone who's already done all of this.
