Cached Web Content
ISA Server 2000 does not provide information on availability of cached objects to web filters. Bandwidth Splitter uses its own heuristic mechanism for recognition of cached objects. This provides correct results with very high probability. However, this does not fully prevent errors.
The information on whether the object is from the cache or not is available in the Cache Info column of the Bandwidth Splitter connection monitoring pane.
This information is also used by Shaping Rules and Quota Rules that have cached traffic handling options set.
