Integrate OSCache for caching wms/wfs responses
-----------------------------------------------
Key: GEOS-712
URL: http://jira.codehaus.org/browse/GEOS-712
Project: GeoServer
Issue Type: New Feature
Components: WFS, WMS
Affects Versions: 1.4.1
Reporter: Thijs Brentjens
Assigned To: Chris Holmes
Priority: Minor
Attachments: WEB-INF.zip
OSCache (http://www.opensymphony.com/oscache/) can be used as a J2EE Servlet Filter for caching http responses. This can be very useful for (tiled) WMS / WFS output. For some more details about configuration, see http://www.opensymphony.com/oscache/wiki/CacheFilter%20Tutorial.html
OSCache has lots of options (like choosing between in-memory caching or on the file system, several caching algorithms), it's worth checking the documentation and the fiile oscache.properties for some basic settings.
To get it up and running on Geoserver, I've attached a Zip-file with the libs that are needed to include in Geoserver, the properties-file and a web.xml that contains the configuration for OSCache. Just unzip it in the WEB-INF dir and restart Geoserver. Note: caching is done in-memory only and caches don't expire with these settings.
