Important

Versions of Microsoft Internet Explorer earlier than 3.01 do not support this feature, even if you set the cache size to 0. Ensure that your users do not enable the setting in their Internet Explorer Web browsers that prevents protected pages from being cached by their browsers. If users download files or attempt to run an application on files from the protected resource, the files will be downloaded to the cache on their computers. However, the files will be cleared from the cache before users can open the files. As a workaround, instruct your users to enable the setting for clearing the cache in their browsers.
Enabling this option will only prevent caching of protected data on the browser. It does not prevent caching of protected pages on the ISA Server computer.
