Having maxAgeSeconds=300 will make all nodes be removed after 300 seconds, disregarding whether a node has been used e.g. 20 seconds ago. anonymous wrote : Unfortunately, we expected that individual elements would expire after the time Having setMaxAge=0 and timeToLive=300 would cause all the nodes that were not 'touched'(get the node, add a key/value to the node etc) for 300 secs to be evicted. e.g. if a node is touched every 200 secs it will never be evicted.
