ThinApp URL lock

Hello,

I successfully created a IE6 ThinApp to run an older version of Javascript required by our company application. I was wondering if there is a way to lock that ThinApp client so that it can only access one specific URL. We want our employees to use the ThinApp client for opening the company oracle app and nothing else. I am just not sure if that is something that i can do from inside ThinApp or if I need to administrate that from our Active Directory.

Thanks in advance.
