Predefined cache levels default values

You can choose from the following predefined cache levels:
• Conservative – This level reduces Internet traffic and decreases the possibility
of the cache returning stale information, but it also minimizes the
effectiveness of the cache. Select this option only if your users are having
problems receiving fresh data.
• Moderate – This level extends entry expiration times to further reduce
Internet traffic and allows cached responses to CGI and query requests. This
is the system default.
• Aggressive – This level further extends expiration times and allows cached
responses to CGI and query requests. This level provides the most bandwidth
savings.
