This is a tracking ticket for issues related to the mechanism for upgrading from HTTP/1.x.

As per our charter, this is:

A negotiation mechanism that is capable of not only choosing between HTTP/1.x and HTTP/2.x, but also for bindings of HTTP URLs to other transports (for example).

Current plan:


    • use NPN (or its replacement); uses OPAQUE TOKEN to negotiate
    • then send magic + SETTINGS
  2. HTTP URLs
    a. existing connection / new connection without context
    - Upgrade Dance; uses OPAQUE TOKEN to negotiate
    - then send magic + SETTINGS

    b. new connection with context (e.g., because you used DNS hint, header hint, prior knowledge)

    • NO upgrade dance
    • first send magic + SETTINGS
