I've not tried this in Tomcat, but here's a thought. According to: http://tomcat.apache.org/tomcat-7.0-doc/config/valve.html#Remote_Address_Filter Tomcat uses java.util.regex for pattern matching. This means that if you want a string regular expression to include a ".", you'll end up entering it as \\. Try using "127\\.0\\.0\\.1|::1" and see if that fixes your problem. I have no idea why it would work in previous versions (have not checked the change log). . . . . just my two cents. /mde/ --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
