  • Eclipselink and update trigger on multiple access to the database

    - by Raven
    Hi, in my project I have a database which many clients connect to. Concurrent access and writing works well. The problem now is not to reload the data every second from the database to always have the current status of the data. Does Eclipselink provide a trigger mechanism on (automatically?) reload the data if the database is changed? How would one use this trigger? Thanks!

  • Can I use IP addresses to limit API access

    - by ed209
    I have a mini API that is only for an app I have built. The API service is on a separate domain to my app. I make jsonp calls to it and receive json in return. Therefore I only want my app to be able to access it. Can I just list a series of IP addresses for my app and allow them? Is there a better way to stop requests from anyone else to my API?
