Hi there,

in the meantime Roy has addressed the main part of the issue, clarifying 
that conditional request header fields apply to many methods other than GET.

I still think it would be good to say more about the default case, though.

Right now, the spec says:

"The new method ought to describe whether it can be made conditional 
(Section 5.2) and, if so, how a server responds when the condition is 
false." -- 
<http://greenbytes.de/tech/webdav/draft-ietf-httpbis-p2-semantics-latest.html#considerations.for.new.methods>

This invites more special cases. Can't we simply state that *all* new 
methods can be made conditional, and describe the default behavior for 
the conditions?

Best regards, Julian
