GeoWebCache Description

GeoWebCache is a cache for WMS tiles implemented as an HttpServlet in Java. GeoWebCache is a cache for WMS tiles implemented as an HttpServlet in Java. It is run through a container like Jetty, Tomcat or JBoss. The response time is measured in milliseconds.ConfigurationIn addition to the GeoWebCache.properties file, GeoWebCache also uses properties files for commons-logging and cache configuration. Included are sample files for setting up commons-logging with log4j and configuring the JCS cache.RunningCopy the war file into the webapps directory of your application server. GeoWebCache should be available at http://server:port/GeoWebCache/GeoWebCache . There is sample OpenLayers interface (if you have a Geoserver deployed alongside GeoWebCache and topp:states available) at http://server:port/GeoWebCache . Also included is src/docs/JCSAdmin.jsp, a basic cache viewer-- copy it into src/main/webapp (or copy into a running web application root folder) to use. . What's New in This Release: · Fixed content type check for image/png formats. Anything that starts with image/png is now accepted as a reponse from the WMS server · Fixed image/png mode=24bit; , the space in this format was previously no correctly encoded · Fixed metatiling bug in seeder. The tiler did not start at the closest metatile boundary and could stop prematurely. This mean that slightly less than one metatile could be missing on the upper and right hand edges of the area that was requested to be seed. This would then get dynamically seeded in most cases, so it was difficult to notice. · Added support for format modifiers. See below · Added support for gutter. See below · Switched H2 database to auto mode by default. In theory this means that more one GWC instance can use the same cache directory. · Added GWC_BLANK_TILE_PATH , a variable that can be set in the environment or web.xml. It allows you to specify what image file is to be used instead of the standard 8 bit transparent PNG. Note that content type response is currently hardcoded to say image/png. · Fixed KML service linking to tiles below the specified zoom level. The hierarchy now stops as defined in the EPSG:4326 grid
