We have a plan to create a new section to our website - one that will feature HTML5 video. During the initial tests we've done, HD video encoded with Zencoder and stored on Rackspace Cloud Files and delivered by their CDN works really well, really fast and really smooth!
However, in PHP/htaccess there is an option to stop hot-linking that basically says, only allow delivery of the file if the request originated from the host server. Does anyone know of something similar that we could use / implement to prevent the various files from being delivered to alternative sites.
The situation we don't want to get into is where somebody grabs the CDN code, and hot links to the video from a web forum or other website. But, having said that, i'm not totally sure we can prevent it.
Does anyone have any thoughts?
