For a client to download from the internet you’d have to have direct downloads setup as Orbiton alluded to. If that’s setup then you can see if a file is downloaded directly from the internet by looking at either the client debug log or you can create a smaller, easier to manage log file using the “_BESClient_JobThread_DebugOutPath” client setting on the endpoint in question and set it to the path and filename you like. Make sure the path already exists though. I tuck mine away in the client logs folder but it could really be anywhere. That log will show you if a file was pulled from the internet or not.
