Any Filtering Mehod for some specific user?

[byemen]

Hi there~
Im making an application using Java & javascript

Is there any way to filter some specific subscription?

here is my scenario.

User A sets to get subscriptions category AA and BB
User B sets to get subscriptions category AA and CC

in my java side, i select data from a table include AA, BB and CC

Both users A and B are seeing a same page
myClient = new LightstreamerClient("http://localhost:8999","HELLOWORLD");

User B doesn't want to get a category BB subscription.

Should I filter from the javascript side?
