Why is this important?
During work with the add-in, it can happen that the add-in tries to contact a Cryptshare Server (Server B) different to the one it is hosted on (Server A) as the user may have received a transfer from this server. As this is a CORS request, the user now would see an error screen:
In order to avoid this screen for future transfers and other users, the administrator of server B must add the requesting domain to the CORS configuration of their server.
