Fwd: I-D Action: draft-ietf-httpbis-cache-digest-02.txt


Today I've submitted a new revision of the Cache Digests draft. Please
let us know what you think.

Three notable changes have been made from the previous version:

* added definition of Cache-Digest header (for using Cache Digest on
Service Workers)
* introduced ACCEPT_CACHE_DIGEST SETTINGS parameter for negotiation
* changed intended status to Experimental

Regarding negotiation, the expected behavior is for the client to:
* use TLS 1.3
* for 1-RTT handshake, wait for ACCEPT_CACHE_DIGEST frame before
sending a CACHE_DIGEST frame
 * and record the value of ACCEPT_CACHE_DIGEST parameter in the TLS
session cache
* for 0-RTT handshake, send CACHE_DIGEST frame at 0-RTT if suggested
by the value of ACCEPT_CACHE_DIGEST parameter stored in the TLS
session cache

Note that waiting for ACCEPT_CACHE_DIGEST frame in the 1-RTT handshake
case will not increase the latency since it is the server that talks
first in the case.

   This specification defines a HTTP/2 frame type to allow clients to
   inform the server of their cache's contents.  Servers can then use
   this to inform their choices of what to push to clients.
