[OpenLayers-Users] Redraw WMS-Layer Double Buffered?

[Christian Schanz]

Hello,I want to reload a tiled WMS Layer with changing data every few
minutes.
At the moment I am simply using

myLayer.redraw(true);

The result of this is that the tiles of the layer disappear. Then it takes
some time before the new tiles arrive. And then finally the new tiles show
up.

Is there a possibility to keep the old tiles until the new ones are
downloaded?

Thanks,
  Christian
