chrome.exe --host-rules="MAP * localhost, EXCLUDE cnn.com" . Possible to start Chrome with this syntax?

Hi,

Been trying out the Chrome Lockdown tool for a few days and really like it! I only miss the feature to be able to Whitelist sites, and when going to another site that is not Whitelisted will get an Custom error page with an auto redirect or link to the page he or she should be locked on.

Its possible to do without  the application via chrome.exe --host-rules="MAP * localhost, EXCLUDE cnn.com"  

Is it somehow possible to get this working?

There is a white list feature in Secure Lockdown - Chrome Edition. See the Chrome Lockdown > Allowed Sites section. Also, be sure to use the free Inteset Chrome Kiosk Helper extension.
