We have a setup that contains 4 geoserver instances being hosted in JBoss across 2 machines. We also have a load balancer machine which contains an Apache Server and a Tomcat Server. Our environment contains a GeoWebCache instance that has all of the requested layers configured. Each layer has 4 WMS URL’s specified (1 for each geoserver instance serving the tile).
It has never been a problem in the past but over the last month our load has greatly increased. In doing some load testing we determined that the vast majority of the incoming requests to the GeoWebCache are going to the first configured WMS URL in the geowebcache.xml for each layer. Is there any way to configure GeoWebCache through the geowebcache.xml to balance the requests across all 4 of the WMS URL’s that we have configured? Also, please note that there is 1 layer that gets more traffic than all of the rest.
