Embodiments of the invention provide a method, system and apparatus for centralized session management in an aggregated application environment. In one embodiment, a centralized session management method can include aggregating a set of applications in a host aggregation environment. Subsequently, each of the applications can be centrally kept alive so as to avoid a time out condition in any one of the applications so long as interactivity is detected within any one of the applications or within the host aggregation environment. In one aspect of the invention, the aggregating step can include aggregating a set of portlets in a portal environment.
