Re: [Ietf-caldav] Last Call comment on Etag requirements in draft-dusseault-caldav-12

[Wilfredo Sánchez Vega <wsanchez at wsanchez.net>]

  Not really, no.

  HTTP defines ETag.  An HTTP server should be able to use the same  
ETag logic on all HTTP resources, and not treat ETags for calendar  
resources differently than others.  Not all users of ETags are going  
to be aware that calendar resources are special.

  My concern is that if there is *any* inconsistency between the  
general solution when it comes and CalDAV's, that an implementor may  
have to choose between being compliant with CalDAV or the more  
general ETag spec, or may have to continue to implement special  
semantics on calendar resources for purposes which are better served  
by the other spec.

  I realize that "the other spec" doesn't exist today, and that this  
is a total drag.  Can't we take your one paragraph and put it into  
its own document?  IFrom ietf-bounces at ietf.org Thu Jun 29 08:22:51 2006

  Actually, I remember sending a few emails with feedback on this  
and not getting any replies, and then I went on my honeymoon, so it  
wasn't quite on my mind for a while.

  I think that document is the way to go, even if all it ends up  
saying is something similar to what you have in the CalDAV draft.

Content-Tra don't know IETF process very well, so I don't  
know what the next steps should be, but as an implementor, I'm  
uncomfortable with the prospect of dealing with two independently  
written specifications for the same behavior.
