We try to avoid that. If you can afford to have long sessions:

QCComponent>>renderKeepAliveOn: canvas
	| cacheTimeout |
	cacheTimeout := self session application cache expiryPolicy 
configuration at: #cacheTimeout.
	canvas document addLoadScript:
		(canvas jQuery ajax
			callback: [];
			interval: (cacheTimeout - 60) seconds)

And then in the application

QCApplication>>renderContentOn: canvas
	self hasKeepAlive
		ifTrue: [ self renderKeepAliveOn: canvas ].
	self renderHeaderOn: canvas.
	super renderContentOn: canvas
