LocalStorageCommandHandler: Copying between different URLs

We are using the LocalStorageCommandHandler. Copying works between different tabs and windows, but does not work when the URLs have a different hostname.

We would like to have the feature of copying selections between acceptance and production applications. Is it possible? Which changes have to be made?

HTML Standard says that localStorage is per domain and per protocol. So I think you will need to use a different mechanism.

thx for the clarifying link.
