Wei asked what deployment plans there are for CVMFS and XCache.

Jakob suggested that the possible use-cases could be larger data distribution: the data federation architecture or conditions databases.

Clients can connect to Xcache using HTTPS, but Xcache can only talk to its origin using XRootD or HTTP.

Wei: Xcache can be deployed as a site-wide cache for CVMFS. This could be a continuation of the XRootD cache plugin for CVMFS.

Radu: Since clients can only read from Xcache, not write into it, does the XRootD cache plugin need to be configured as part of a tiered cache?

Michal wanted to know the status of the xrdhttppss branch. There is still a bug in the Cache Context Management API. Need Andy's help. Most likely it will be merged for XRootD 4.9.

ATLAS week @ CERN next week (Oct 1-5). We will meet in person at the CERN and continue the discussion.
