The present invention relates to an anti-reflective coating composition that can be used to form at least two layers by a single coating process and is allowed to provide an anti-reflective coating film having more improved interface adhesion between the formed layers and scratch resistance, and an anti-reflective coating film manufactured using the same. If a user is likely to commence use of a content item through a client, and if the client has available resources to facilitate instantaneous use, the client is configured to predictively cache the content item before the user commences use. The latch is displaceable to a retracted position in which the hook can be snapped over the adjacent structural element of the structure.
