The remote repository at the URL you specified is hosted by another instance of Artifactory. This exposes additional capabilities you may configure:
If set, download statistics for the artifact at the remote Artifactory instance will be updated each time a cached item is downloaded from your repository.
If set, properties for artifacts that have been cached in this repository will be updated if they are modified in the artifact hosted at the remote Artifactory instance.
If set, Artifactory lets you navigate the contents of the repository at the remote Artifactory instance for all package types, even if the artifacts have not been cached in this repository.
If set, you will see an indication if a cached artifact has been deleted from the repository at the remote Artifactory instance.
These settings are also available in the Edit Repository screen.
