Alt-Svc #71: Hints for Flushing


Mike suggests that a hint in Alt-Svc as to whether it should be flushed on a network change could be helpful. 

Extrapolating, I think this could be a boolean flag, e.g.,

  Alt-Svc: h2=":443"; ma=3600; persist

(if we change the parameter ABNF to make arguments optional)


This is an interesting discussion to have in concert with #69 regarding extensibility; if we make services containing unrecognised extensions must-ignore, it would make this sort of thing much chattier; the above as an after-the-fact extension would need to be this on the wire:

  Alt-Svc: h2=":443"; ma=3600, h2=":443"; ma=3600; persist
