Hey All,
I am going to be starting up a new project where I host video files on a web site. I want to make sure that people cannot go to the site, download the video file and then never visit again. Instead, I want to make it so if they want to view the file again, they have to revisit my site. I assume this is what youtube, google video & Daily Motion all do. How do you suggest I go about doing so?
