- WMS services are configured via an XML file - geowebcache.xml, but DDF will utilize the GWC REST services with an admin UI plugin
- the configuration can be reloaded at runtime using the geowebcache//rest/reload endpoint
- Disk quotas can be configured via an xml configuration file. See (http://geowebcache.org/docs/current/configuration/diskquotas.html)
Security
GWC utilizes spring security for its endpoints. Luckily, security can be disabled by modifying the spring security config (WEB-INF/acegi-config.xml). DDF security works with the GWC endpoints as with any of the other DDF endpoints.

| Element | Example Value | Description |
|---|---|---|
| name | layer1 | The name of the layer that GWC should respond to. It is equivalent to the value of LAYERS= in WMS requests, and can contain commas. See wmsLayers |
| mimeFormats | <string>image/jpeg</string> | List of formats to be supported. These must be known to GeoWebCache. Legal values are image/png, image/png8, image/png24, image/gif, image/jpeg, image/tiff, gml, application/vnd.google-earth.kml+xml, application/vnd.google-earth.kmz+xml |
| wmsUrl | http://example.org/wms | A list of URLs to backend servers than can render tiles for this layer. They are used in a round robin fashion for load balancing and automatic failover. The only time you can ommit this element is if you expect the layer to be merged with that from another source. |
| wmsLayers | layer1,layer2 | The LAYERS parameter sent to the WMS backend. It may contain commas, to request composites of several layers from the backend, and be different from the name element. |
| wmsVersion | 1.1.1 | The VERSION parameter sent to the WMS backend. The default is 1.1.1 |
| tiled | false | The TILED parameter sent to the WMS backend. The default is FALSE, you should generally not change this. |
