What is the proper way to apply a custom filter to a comet chat

[Oleg G.]

Hi all,

I'm trying to add a filter to a comet chat, i have different kind of
messages, everything else is based on the lift's comet chat example.
So there are some checkboxes to exclude certain kind of messages, all
is working but currently i'm updating all listeners of the ChatServer
every time someone changes their filter. I've looked through API docs
and source code and couldn't figure out a good way to only send update
to one session.

Any hints?

You might try looking at the code that I wrote for the CUFP Lift tutorial... it gives you multiple chat rooms... while this isn't filtering, it'll give you an idea of how to do things differently on a per user basis.

Personally, I'd do all the filtering in the CometActor rather than doing the filtering in the chat server.  That way the logic is per user rather than global.

Does this help?

Thank you, David.

The sample code helped. The key is to keep a session->actor map (or
session var) to target the updates, i was not sure if it is a good
solution until i've seen your code.
