We have a websocket application which keeps writing data to the clients.
We found that when tabs (not whole browser) of Firefox (ver. 22) is closed, the websocket connection is not closed. Anyway, reproducibility is very low. And the sendQ (netstat -an) keeps growing
So, what we did is. we kept sending heart beat from client. If this heart beat timeout occurs, we are trying to close the connection as follows
ByteBuffer bbuff = ByteBuffer.allocate(1);
Is this correct approach to close the connection from server? Because, the connection is not closed at lower level (netstat -an). Anyway, writing data to it , is stopped and sendQ stops growing.
# netstat -an | grep :8080
