If you choose the custom settings option, the Web Sites panel becomes active and you can enter unique
URLs. URLs must begin with www and end with a valid suffix. The Acrobat family of products maintains a
white and black list of URLs called the Trust List. Users can specify whether or not URL access is allowed
on a global or per-URL basis.
Manage Internet Access dialog
For URLs that aren't explicitly trusted or blocked (they are not on the white or black list), a warning
appears whenever a document tries to access the Internet. When you check Remember my action for this
site, the site is added to your URL white or black list.
