Class StaticAssetCacheFilter

java.lang.Object

org.alfresco.web.scripts.servlet.StaticAssetCacheFilter

All Implemented Interfaces:

javax.servlet.Filter

public class StaticAssetCacheFilter
extends Object
implements javax.servlet.Filter

Simple servlet filter to add a 'Cache-Control' HTTP header to a response. The Cache-Control header is set to a max-age value by a configurable setting in the 'expires' init parameters - values are in days. WebScripts or other servlets that happen to match the response type configured for the filter (e.g. "*.js") should override cache settings as required.
