Thanks a lot Dan, and it's obvious that I misunderstood something. I've
looked into several technical or non-technical descriptions, but seen
nothing about how to really activate the feature, such as commands or
configuration files, but potential benefits from it. As a result, I think
such a process takes place automatically without user intervention. After
all, thanks all for the quick response!
