Package org.alfresco.web.scripts.servlet
Class StaticAssetCacheFilter
java.lang.Object
org.alfresco.web.scripts.servlet.StaticAssetCacheFilter
- All Implemented Interfaces:
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.
