Sven or anyone else with experience with ZnWebSockets, a question regarding ZnWebSocket usage. I have the following code which sort of resembles my current usage of ZnWebSockets. ZnWebSockets are used for both sending and receiving messages in a random fashion (ie, no request-response like pattern). Because the ZnWebSocket operates synchronous I fork 'handlers' which process the incoming messages. When executing the code below, the client closes the connection but will 'recognise' this itself only after a timeout (around 30 seconds by default). Is there a better way to use ZnWebSockets which does not incur this delay? My current workaround (see comment at the bottom in code below) is to send an explicit "close" ZnWebSocketFrame instead of sending #close to the ZnWebSocket. This will have the client close 'directly', after which I can close the ZnWebSocket stream explicitly. The implementation of #close for ZnWebSocket is to perform both: send close frame and close stream. The later seems to 'stall' the receive message until timing out. The synchronous handling of incoming messages might be causing this. But could not directly find why closing the stream resulted in different behaviour than when only sending the close frame. (Hope this explanation is helpful ;-). -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
