[xmlblaster] Initial updates question

["David Hooker" <dhooker at btrade.com>]

Hi-

I want to subscribe to a topic and get only those messages which I
haven't seen yet.

For instance, suppose my client dies, and someone publishes some
messages on a topic.  Let's say that the messages have a lifetime of 1
day.

Now, when my client comes up, I want him to get initial updates of only
the new messages he hasn't seen yet.

How do I do this?  Is there API support in xmlBlaster for this?  If not,
how can I implement this in my client?

Thanks.
