Dear all,

I have made my stab on the description of the 2-ways and the 4-ways 
handshake proposal. See 

All comments welcome! I asked some questions (regarding the first HTTP 
response code in the 4-ways handshake). The pro/cons need also to be 
completed. In particular, I'm not sure about the cachability of the 
resource in both cases?

If the cachability is the primary concern of the 2-ways handshake, I 
observe that a UA can always use the 'Pragma' header and state a 
no-cache value, expressing the fact he might prefer to have only one 
roundtrip and no cache rather than 2 roundtrips. What do you think?

My main references were the excellent summary of Silvia sent a while 
back on this list [1] and the unvaluable help from Yves that I have 
bothered with 50 emails :-)
It is a wiki, so now, all, modify the page at your convenience :-)
