[jetty-users] WebSocket auto disconnect after 30sec ?

[go canal <gocanal@xxxxxxxxx>]

I am not sure this is a browser issue, I am using Chrom. WebSocket is automatically disconnected after 30 sec. 

it is mentioned http://www.therichwebexperience.com/blog/greg_wilkins/2009/11/jetty_websocket_server 

what's the best practice of keeping the connection ? keep sending 1-byte dummy data ? that's sounds unacceptable....
 

rgds,
