    Cancel existing subscription

    Is there a method from and Adapter to cancel an existing subscription? We have a use case where the data point a subscription is 'monitoring' will expire. We want to force a cancellation of the subscription.

    Hi rthompson,

    Yes, please refer to this listener provided by the Lightstreamer server to receive requests about sessions and any asynchronous severe error notification:
    https://sdk.lightstreamer.com/ls-ada...ntrolListener)

    Please note that it is a feature relatively recently added and so you should make sure to use a version of the Java In-Process Adapters 7.2.0 or higher.
    If, on the other hand, you use a remote library, please note that not all libraries already have this feature.

    Regards,
    Giuseppe

    Hi rthompson,

    Sorry, I missed to mention that in the specific case of terminating a subscription the callback to be invoked is in the TableInfo object paassed in the notifyNewTables.
    In particular the forceUnsubscription method.

    Anyway, you could also refer to this post for a general discussion on the topic: https://forums.lightstreamer.com/showthread.php?8786-Forcing-subscription-termination&highlight=forcing

    Regards,

    We are using C#. I didn't see the forceUnsubscription method on the TableInfo object. It isn't clear how to extend the class to add that functionality.

    Hi rthompson,

    Yes I can confirm that the feature has not been ported to c# remote library yet.
    In this case you should consider the workaround suggested in this post: https://forums.lightstreamer.com/sho...ll=1#post15065
