I have a MapCache <-> MapServer setup and running. MapCache is configured for WMS access and is used to cache tiles for specific layers provided by my MapServer. I can access the WMS capabilities and display a tile through my browser by accessing WMS trough MapCache and have verified that it is being cached.
Excellent, just what I wanted.
Next, I setup a WorldWind client to access the MapCache WMS. WorldWind complains that the rootlayer (something MapCache uses to wrap all layers) does not provide a geographic bounding box. WorldWind logs this as severe and starts throwing exceptions. I'm trying to figure out where the problem lies. Does the WMS OGC Standard require the top layer to have a bounding box or is the WorldWind client not WMS compliant? Below is the error messages that I'm seeing. Below that is the getCapabilities response. Below that is the MapCache xml file. Below that is the MapServer map file.
Any help will be greatly appreciated.
