WebDAV WG Meeting 58 th IETF, Minneapolis

Agenda Agenda bashing ACL status Quota Redirect draft Interop report RFC2518bis issues PATCH proposal

ACL status In RFC Editor queue Note that Security ADs did not approve ACL although they did not block it –Allowing different servers to support different sets of privileges makes automated clients or audit tools difficult to impossible –Need to plan interoperability tests –Can we lock this down more in the future?

Redirect draft Draft-ietf-webdav-redirectref-protocol-06 Replace MKRESOURCE with MKREDIRECT? Allow authoring of 301-type redirects as well as 302-type How to handle requests that address multiple resources, including redirects –207 may confuse –HTTP/1.1 says requests to redirects MUST result in 3xx status code

Interop Report Performance tests (first time) Three commercial clients, one open- source Six commercial servers This is only about 30% of implementors –Attendees of previous interops did not necessarily show up

RFC2518bis issues Do namespace prefix tags need to be preserved Requirements for ETag support Must resources be in collections Some interest in new writable modification-date property –Whether these change on MOVE Plan for another draft in next couple months

PATCH proposal: use cases WebDAV: large files –Adobe and Apple client implementors asked for this DeltaV: small changes to many source files SIMPLE: changing my buddy list or presence document on HTTP server Netconf? Making changes to large configuration documents
