Fluent NHibernate Cascade - Which side?

In using Fluent NHibernate, I can't seem to find a good explanation of when you use the cascading option on the References side vs. the HasMany side.

What's the difference (if any) in mapping the following...

References(...).Cascade.All();

vs

HasMany(...).Cascade.All();

My question stems from a problem when saving a parent (root) entity. Once it's saved, I want to insure that all child objects are also persisted.

You put the cascade on the side that you are saving.

If you save the parent and want to cascade to the children, put the cascade mapping on the parent.
