Etag-on-write, 5th attempt (== IETF draft 04), was: I-D ACTION:draft-reschke-http-etag-on-write-04.txt


(see below for the announcement, and 
for an HTML version).

This draft tries to address the feedback I received from Wilfredo 
Sanchez Vega. Note that I decided not to extend the draft to cover weak 
entity tags, though (it is compatible with them, but doesn't use them in 

In the absence of new feedback over the next few days I will submit this 
one to the RFC Editor for publication as Experimental Standard.

Best regards and thanks for the feedback so far,
