Abstract
There is provided a method of providing cached content in a telecommunications network. The method comprises requesting content from a caching system (S12.1). At a local cache (305), fragments are associated with the requested content (S12.5) and sent towards a user (S12.6). An identifier for the user and any of an identifier for the requested content and an index of each identified fragment is sent towards a mirror cache upstream of the local cache (S12.7). Prior to the local cache (305) identifying the fragments associated with the requested content, the mirror cache may identify fragments associated with the requested content (S12.3), and send a key comprising the index of each fragment to the local cache (305) (S12.4). The fragments will then be identified at the local cache (305) (S12.5) using the key.
