- * attempts for the broken resource, thereby avoiding expensive but useless network IO. The error marker is considered
- * stale once the repository's update policy has expired at which point a future resolution attempt will be allowed.
- * Error caching considers the current network settings such that fixes to the configuration like authentication or
- * proxy automatically trigger revalidation with the remote side regardless of the time elapsed since the previous
- * resolution error.
