Systems and methods are provided for determining engagement information related to client devices that have downloaded at least a portion of media content. In some embodiments, a server may receive a request for a playlist of media content from a client device. In response, the server may send a first portion of cookie to the client device. The server may receive a request for a fragment of media content with the first identifier value from the client device. In response, the server may determine that the request was received with the first identifier value and may increment a counter that represents a number of unique client devices that have downloaded at least a portion of the media content. The server may also send a second portion of the cookie to the client device that indicates that the client device has already downloaded at least part of the media content.
