Hi all,

As the main spec is almost done, shall we resume work on compression?

Here's the latest draft of per-frame deflate compression extension.
http://tools.ietf.org/html/draft-tyoshino-hybi-websocket-perframe-deflate-04

Based on input from the list, this spec includes
- inter frame compression context sharing
- COMP bit
-- so that we can turn off compression for data that doesn't compress well
e.g. small frames
- LZ77 window size option
-- so that endpoints with memory limited can ask the other peer not to use
big window size
- frame-by-frame compression option
-- for intermediaries that just cut and dispatch frames to backends but
don't want to do much work e.g. load balancer
- overhead elimination proposed in RFC1979

Thanks
Takeshi
