Media Flow Controller Administrator's Guide
(Optional) Specify a list of policies for data requested from origin with delivery protocol http;
enters you to namespace <name> origin-request mode, use exit to leave, use no
namespace <name> origin-request to re-set configured values to defaults.
Notes:
•
cache-revalidation
revalidation prior to deleting expired data by choosing permit, the default; and, optionally,
use-date-header for revalidation if the Last-Modified header does not exist. This allows
Media Flow Controller to proactively talk to the origin when the content is close to its expiry
(20% of life left) due to a pre-set cache age, and ask for revalidation. Doing this can save
network bandwidth toward origin as the entire content is not fetched, and only the headers
need revalidation. To have Media Flow Controller delete content that has attained its set
cache age, choose deny.
