>> What were Range requests built for?

notes that restarting partial downloads was also an original motivation. 

For some reason,  I had expected the web to migrate to using
compound documents
http://en.wikipedia.org/wiki/Compound_document

but to avoid having to download the entire package before you 
could start  rendering.  

I think MPEG-Dash designers considered using range retrieval
but decided it was too unreliably available (many proxies
not doing range retrieval right).
