I am trying to address some latency issues accessing US based servers from Asia

We are using GeoWebCache in front of two GeoServer instances, based in the USA.

One thought that occurred to me was to deploy additional GeoWebCache Servers, but instead of having them hit a GeoServer instance, locally or remotely, have them front another GeoWebCache instance (Cascaded) located in the USA.

The thought behind this is that the tiles will already be cached on the "Master" GeoWebCache which simply serves the requested tiles to the GeoWebCache instance requesting it in Asia. This should eliminate the need to have additional Geoserver Instances to service Tile requests

Has anyone done this before or have any thoughts as to whether it will work as I expect?
