CAUTION
Most ISA changes do not require the firewall service to be restarted. Changing the

Changing Default Cache Settings
To process cache objects, ISA Server 2006 uses a series of default settings. To access and
modify them, click on the Configure Cache Settings link in the Tasks tab of the Tasks
pane. The Cache Settings dialog box, shown in Figure 8.5, contains a General tab that
displays the size of the cache, as well as an Advanced tab.
The Advanced tab allows for the customization of the maximum size of URLs that can be
cached, and whether to cache objects with an unknown last time that they were modified.
