openlayers3 - prevent duplicate layers

[المشرف العام]

after i create a map in openlayers3(with geoserver), when i zoom out, it duplicate all layers as you can see also in the following example: http://openlayers.org/en/v3.2.1/examples/drag-rotate-and-zoom.html

(i don't want the user to be able to drag the map left/right till infinity)

how can i set the extent (to the whole world) so i will not see the duplicated layers?

thanks!
