Hi,

sorry for this late reply, but it took me until today to find some time 
to see what is going on here.

I assume you refresh your layer by saying layer.refresh(). Instead, it 
would be enough to say layer.refresh({force: true}). No need to change 
the update method of the strategy.

Explanation: options in update() is the function argument, and calling 
layer.refresh({force: true}) will trigger the layer's refresh event with

an event object that will be passed to the strategy's update method, 
which will be executed on the layer's refresh event.

Regards,
Andreas.
