I have a PostGIS database that gets updated about once every two hours. Since Geoserver datastore do not do any caching, I was looking for service does that and i found GeoWebCache REST API http://geowebcache.org/docs/current/rest/seed.html
from what i understand, its the only option for caching updated (new) data. am i right? and is there any detailed example on how to apply it?
I am using openlayers, with wms
