I am using Apache as web server and the return code is always HTTP/1.1 200. I want to set some kind of handler or use a mod to return HTTP/1.1 206 when the extension of the file requested is .mp4 so it can do video seeking, my web server is already returning some headers to do seeking, but it doesn't work.

Is this possible?

The HTTP headers

http://*hidden*/media/movies/file/1080/d3191cd83109c593ec908f3a47efa8a2.mp4
