ABSTRACT:
An information processing apparatus, a session recovery method and a recording medium for storing a session recovery program are disclosed. According to one aspect of the present invention, even if a session with a server apparatus connected via a network is invalidated, it is possible to resume the session without user's recognition of the session invalidation. The information processing apparatus includes an authentication information maintain part maintaining authentication information supplied to establish the session, a session invalidation detection part detecting that the session is invalidated, and a session recovery part, when the session invalidation detection part detects that the session has been invalidated, requesting the server apparatus to establish a session by using the authentication information in the authentication information maintain part.
