-Alt-Svc is a suggested extension with a corresponding frame (ALTSVC) in HTTP/2
-that tells the client about an alternative "route" to the same content for the
-same origin server that you get the response from. A browser or long-living
-client can use that hint to create a new connection asynchronously. For
-libcurl, we may introduce a way to bring such clues to the applicaton and/or
-let a subsequent request use the alternate route
-automatically. [Spec](https://tools.ietf.org/html/draft-ietf-httpbis-alt-svc-14)
