Thank's David.

You know any example code how to implement a scale-dependent WMS layer?.

Thank's again.

Antoni,

If you also control the WMS and are serving up your own data, you
could use a scale-dependent WMS layer as your source.

You could also potentially build a WMS layer that cascades the data
from the two external WMS', using scale to determine which data source
to use.  That said, this would likely be a performance hit, you would
probably do better to write some custom javascript code to accomplish
it on the client side.

David.
