Hello,
I am using module websocket and it works very well.
However I would like to send BYE to the other end if event [websocket:closed] happens.
From the docs I can see websocket module itself doesn't provide for this.

I was considering doing something like this:
  - use module htable to match $si:$sp to dialogs
  - use event_route[dialog:start] to insert dialog info to my htable under $si:$sp of Websocket side of the call
  - use event_route[dialog:end] to remove dialog info from htable
  - use event_route[websocket:closed] to iterate over entries in the htable under key $si:$sp and call dlg_get() and dlg_bye().

Obs: in the above, there is a risk of losing some dialogs as insertion in htable cannot be done atomically, but I am fine with it as it it not expected to happen as WebSocket users would only infrequently generate simultaneous calls. 

However before going with this, I would like to ask for other possible approaches.

Regards,
Takeshi
