Think of it as a slight 'bending' of the rules.

From an application developer's viewpoint, it IS stateless.

Some application developers use keep-alive to improve performance and reduce resource consumption of embedded system. When server returns keep-alive it means for a client to continue using the same connection. However it doesn't mean that the same servlet will continue to service it.
