All - I'm trying to find the best way to create an allowed list or "white-list" . I've used a method that requires me to create a flavors and zones but that messes up my RDRs, directing traffic through the service I created using the zone and flavor.  I found another method, where subscriber redirect, where I can specify allowed URLs  and redirect to a portal of some soft for URLs not in the list.  

Is this the best way to acoomplish this? 

Does anybody know of any limitation on the amount of URLs  you can add? 

Can I use ipaddress and urls as well? 

Thanks!
