Hi!
Is it possible to implement the following:
1. User requests some VOD file
2. Server gives user a small preroll video (5 sec), and what this video will be - depends on what video was requested and query string of the request.
3. After preroll end the user starts watching requested VOD file.
(!) What is important - no special client-side coding should be done for this.
I understand that it is not so trivial, but I hope solution(s) exists.
Thank you!

This post shows how to do this server-side with no client modification:
