What is draft-ietf-webdav-quota?

• WebDAV servers are frequently deployed with
  quota (size) limitations. This Internet-Draft
  discusses the properties and minor behaviors
  needed for clients to interoperate with quota
  implementations on WebDAV repositories.

Whats new in -02?

• DAVquota-limit-bytes replaced with
  DAVquota-available-bytes, aligning it with NFS
• DAVquota-limit-bytes - DAVquota-used-bytes
  quota_avail_hard
• quota-limit was originally chosen so that it
  would be a fixed value, but as Stefan Eissing
  pointed out, this wouldnt be the case when the
  free space on the server goes below a users
  quota.

DAVquota-limit-bytes Example

• quota-used 0
• free space 5GB
• quota-limit 05GB 5GB
• quota-used 0

DAVquota-available-bytes

• is the value in octets representing the amount of
  additional disk space beyond the current
  allocation that can be allocated to this file or
  directory before further allocations will be
  refused. It is understood that this space may be
  consumed by allocations to other files or
  directories.
