Invalidating the data store
The single JVM mode of operation maintains and shares a data cache across all property appropriately, or integrate Open JPA with a third-party caching solution.
Remote commit providers are described in Section 2, “ Remote Event Notification Framework ”.
The end of a web session is usually triggered by one of the following two events: Both cases must be implemented carefully, in order to avoid introducing weaknesses that could be exploited by an attacker to gain unauthorized access.
More specifically, the logout function must ensure that all session tokens (e.g., cookies) are properly destroyed or made unusable, and that proper controls are enforced at the server side to prevent the reuse of session tokens.
Open JPA's data cache is not related to the cache aimed at guaranteeing transaction isolation when operating on persistent objects.
Open JPA's data cache is designed to provide significant performance increases over cacheless operation, while guaranteeing that behavior will be identical in both cache-enabled and cacheless operation.
For details specific to this case see Using a Dispatcher with an Author Server, below.Note: the most important thing is for the application to invalidate the session on the server side.Generally this means that the code must invoke the appropriate methods, e.g., Http Session.invalidate() in Java and Session.abandon() in . Clearing the cookies from the browser is a nice touch, but is not strictly necessary, since if the session is properly invalidated on the server, having the cookie in the browser will not help an attacker.Today’s ECJ’s judgement is the culmination of a 2013 legal challenge by European privacy campaigner Max Schrems who filed complaints against several U. Internet giants — including Facebook — in the Irish courts for alleged collaboration with the NSA’s Prism program.The Irish courts dismissed the complaint, on the grounds that the European Safe Harbor agreement governed such data flows — referring the case to the ECJ.
