We would like to cache tiled map images to a remote storage area and would like Geoserver to retrieve cached images from this location as clients make requests. Here are our questions:
1- Is this possible with Geoserver?
2- If so, what is the file transfer protocol Geoserver uses for storing cached images and retrieving them from the remote location?
3- Is it possible to use multiple Geoserver instances for this purpose, caching to the same remote location?
