We're attempting to use an Akamai Progressive Media Download and HTTP Origin mode to serve up Smooth Streaming VOD assets.

I've enabled HTTP Origin mode and added the Cache-Control headers. That is good, but we'll also need Wowza to return last modified headers, and to properly respond with 304 if the client includes if-modified-since headers.

I couldn't find this being requested elsewhere, which I find curious, as I would think this is a common request for people using a CDN w/ Wowza HTTP Origin.
