My question is about JMS about Durable subscriptions
Durable subscription—A durable subscription is infinite. It’s registered with the topic subscription to tell the JMS provider to preserve the subscription state in the event that the subscriber disconnects. If a durable subscriber disconnects the JMS provider will hold all messages until that subscriber connects again or until the subscriber explicitly unsubscribes from the topic.
What happens with new Subscriptions - Do they get messages from the start?
Are the messages are stored always from the start?
