Implementing `Cache-Control: no-cache` for an HTTP client to trigger cache invalidation would be a handy enhancement. Currently, to monitor that xcaches can reach an origin server, we've needed to deploy cronjobs to remove cache entries of test files. Being able to force a cache to forward the request to the origin would be helpful. In addition, this might help with allowing cvmfs clients to retrieve updated content via xcache. Glancing at the [cvmfs code](https://github.com/cvmfs/cvmfs/blob/1a47970001900f871c54bedad43333c8556b789c/cvmfs/download.cc#L19-L20), it seems to retry with no-cache if there's a mismatch. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1886 You are receiving this because you are subscribed to this thread.
