I'm trying to find high load solution for streaming server. The idea came to me this morning. What about CDN or cloud storage with byte-range support. Basically flash player require only partial video-file transfer from remote server and keep-alive connection.
Does anyone know whether this is a reasonable idea and whether CDNs support it?
CDNs are generally pretty shady about what exact features they support. You'll need to contact them directly and ask whether they'll do what you want, and then figure out which one fits your use-case and budget best.
It turns out that byte-range is a HTTP header for flash pseudo-streaming. I've done some googling about, and found a few articles that suggest that CDNs supporting this are:
Edgecast, Limelight and NetDNA (src)
and Bitgravity, CDNetworks, (src)
