I've incorporated many of the ideas mentioned on the list and in the NYC minutes to create a proposal that (I believe) accomplishes the goals with a minimum amount of change.



Changes:

+ Only the HEADERS and PUSH_PROMISE frames can alter the compression context.

+ CONTINUATION frames can only use hpack literals (optionally Huffman encoded) that don't alter the table.

  - CONTINUATION is flow controlled

  - CONTINUATION has an END_STREAM flag



Benefits:

+ Simplifies CONTINUATION implementation

  - i.e. fixes the nonsensical END_STREAM that doesn't actually end the stream

+ Flow control of CONTINUATION:

  - removes the incentive for implementations to cheat and send large amounts of data in the HEADERS+CONTINUATION jumbo frames

  - may help with certain HOL blocking situations (e.g. connection coalescing)
