Class SetResponseBufferSizeFilter

java.lang.Object

org.kuali.rice.krad.web.filter.SetResponseBufferSizeFilter

All Implemented Interfaces:

javax.servlet.Filter

public class SetResponseBufferSizeFilter
extends Object
implements javax.servlet.Filter

This class can be used to increase the response buffer size so that if there is a late exception, Tomcat's ErrorReportValve can display it on the page and return an error status in the HTTP reponse header. This filter must be configured early in the chain in web.xml, before another filter writes anything to the response. There's no configuration option for this already?
