hey, il get straight to the question here...

While on youtube, and if i wanted to save a video to my computer, i use the activity window to locate the file, and save it...

I need to know how the process is done. Does Safari cache all the content loaded, allowing us to save the video? On an admins computer, they will just see a user "loading" a couple of youtube videos... right?

Or will they see that i am actually downloading a video?

Or does it go to a youtube downloading site and downoads from there?
