• Cache Directive—Choose follow (default) to tell Media Flow Controller to obey the
cache-directive (Cache-control : no-cache or Pragma: no-cache) in the HTTP
header when data is fetched from the origin. Choose override to tell Media Flow
Controller to always cache.
• Content Store Media Cache Age Threshold—Set a time threshold for newly-fetched
content stored in media cache (non-volatile) instead of RAM. By default, new content
with a cache age under 60 seconds is stored only in RAM (the expectation is short
cache-age implies that the content will not be served for too long and is not worth
storing in media cache). To have new content always stored in media cache, set this
value to 0 (zero).
