Abstract
A method in a cache node (30) of a network comprises monitoring a secure data stream being received at the cache node from a server node, and detecting from one or more data chunks of the secure data stream that the secure data stream contains a data object that has been previously received and cached at the cache node, and sending a notification signal to the server node that the data object has been previously cached. The method may further comprise receiving one or more encryption header portions (e.g. TLS headers) from the server node, inserting a previously cached data chunk corresponding to each of the one or more encryption header portions into the data stream, and sending the data stream to a client device.
