A technique for controlling the streaming of content through a network is disclosed. In an embodiment, the technique involves editing the manifest file that is used to implement an HTTP adaptive bit rate streaming protocol. For example, a manifest file is received at an intermediate network device in response to a request from a client for a content element, the manifest file is then edited at the intermediate network device, and then the edited manifest file is sent to the client. In an embodiment, editing the manifest file involves deleting and/or inserting a URI within the manifest file.
