How do I unpublish pages in MOSS when content deployment is used?

Question

Page is published from MOSS content management server to MOSS front end server. Content deployment path is used to publish the page.

I can remove/unpublish page from content management server. But content deployment doesn't remove page from front end server.

I FOUND AN ANSWER FROM:

The reason is that only incremental deployment exports deleted items which is required to ensure that the items also get deleted on the target server.
