You can use the class ProxyInboundSocket.java, this was the one included
with the original commit.
In there find the onClientOpen i.e.
@OnOpen
public void onClientOpen(final javax.websocket.Session
backendSession) {
and update 'backendSession' as follows
backendSession.setMaxIdleTimeout(60000 * 60 * 24);
I would highly recommend to upgrade since your custom settings will be lost
once you upgrade and it will be difficult to keep track as this class does
not exist any more.
Best,
Sandeep
