GeoWebCache

The most common request to GeoServer is to provide an OGC-compliant WMS interface and thus generating maps in raster format. For this reason, caching of these WMS requests may have a decisive influence to the performance of the server and should be carried out on each (productive) system wherever possible. For caching map tiles there is a variety of good open source caching engines available, but here we'll use the GeoServer integrated GeoWebCache (GWC), which acts as a proxy between the client and GeoServer.

In the following sections we'll initiate all required steps to generate a cache for the layer momo:countries:

• Prerequisites
• Configure a new gridset
• Configure a cached layer
• Generate map tiles.
• Check cache directory
• Check cache-headers
