Media Flow Controller CLI Commands
(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
—Specify that Media Flow Controller ask origin for cache age
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.
•
connect
—Set options for connections to the target origin server; applicable only with an
origin-server server-map cluster-map or origin-escalation-map configuration.
•
retry-delay
—The amount of time in milliseconds the request is delayed and retried
after a socket connect timeout. Default is 100 ms.
•
timeout
— The socket connect timeout in milliseconds. Default is 100 ms.
•
header action add
—Specify a header <name> and, optionally, <value> to be added to
the incoming request; up to four headers may be added this way.
•
host-header inherit incoming-req
—Allow (with permit) or dis-allow (with deny)
Media Flow Controller to set the HOST: header in the Media Flow Controller-to-origin
HTTP REQUEST to the value found in the HOST: header in the incoming URL to Media
Flow Controller. Default is deny.
•
read
—Set read options for connections to the target origin server; applicable only with an
origin-server server-map cluster-map or origin-escalation-map configuration.
•
interval-timeout
—The socket plus internal processing timeout in milliseconds.
Default is 100 ms.
•
retry-delay
— The amount of time in milliseconds the request is delayed and retried
after a read timeout. Default is 100 ms.
•
x-forwarded-for
—Allow (with enable) or dis-allow (with disable) Media Flow
Controller setting the X-Forwarded-For header to the value of the client IP address when
requests are sent from Media Flow Controller to origin upon a cache miss. Default is
enable.
