java.lang.Object

net.anotheria.moskito.web.MoskitoFilter

net.anotheria.moskito.web.filters.SourceTldFilter

All Implemented Interfaces:

javax.servlet.Filter

public class SourceTldFilter
extends MoskitoFilter

This filter separates the traffic by source top level domain. WARNING: This producer shouldn't be used in production environment on high traffic sites because the reverse lookup of ip addresses can cost time and the system becomes vulnerable to dns attacks or failures. Use AsyncSourceTldFilter instead. This filter requires reverse lookup to be enabled by the servlet container.
