Does anyone know whether Tomcat has built in support for allowing or disallowing certain IP addresses or network addresses and subnets? Many web servers support this sort of functionality, which is useful for using the web server to serve intranet pages only to an internal network, or for blocking networks that seem to be the source of abusive users.
