How do I set a ban on caching for certain sites?

When ISA creates a forward cache, it may be necessary to disable caching for some sites, such as mail service points, because of security requirements.

Step 1: Start Isa, expand the directory in the left window, select the Cache node, select the Cache Rules tab in the Middle window, right-click the Forward cache rule option that was created before, execute the Properties command, and eject the Forward Cache Rule Properties dialog box.

Step 2: In the "Forward Cache Rule Properties" dialog box that pops up, select the To tab, as shown in Figure 1.
