So my site is SPDY. All of my local assets are SPDY too. But the majority of my assets are served from Rackspace's CloudFiles CDN. This is not SPDY.
Do those files get streamed through SPDY somehow, or are they pulled in via separate laborious HTTP requests?
I currently have these CDN assets split across 3 different sub-domains. Should I merge them all into one (as is the preferred serving method for SPDY files, to cut down on DNS lookups), or should I leave them as they are because they're coming over regular HTTP 1.1?
Thanks, I couldn't find any decent information on this via googling.
