About Subscribed Lists
Lists for use in web security rules can be filled with content that is retrieved from suitable servers. These lists are known as subscribed lists.
When working with subscribed lists, you only have to configure general settings, such as the list name, on your own. For the list content, for example, IP addresses or URLs, you rely on a server, which can be the Skyhigh Security server that is provided for supplying subscribed lists or another server that you specify.
Subscribed lists that retrieve their content from the Skyhigh Security server are known as Skyhigh-supplied lists. Lists that retrieve their content from another server are known as customer-maintained lists.
After you have created a subscribed list, it appears on the Subscribed Lists branch of the lists tree on the user interface. You can work with a subscribed list in the same way as with other lists on the lists tree.
Subscribed lists are limited in size. They must be no larger than 4 MB or contain more than 100,000 entries.
The content is maintained on the Skyhigh Security server. To ensure that Skyhigh Security-supplied lists hold the latest content, you perform manual or automatic updates on the user interface of your appliance.
Retrieving list content from the Skyhigh Security server

Retrieving list content from another server
When the content of a subscribed list is retrieved from a server other than the Skyhigh Security server, you specify the URL for the file that holds this content on the server.
