Which statement describes HTTP header enrichment and its uses?

A.
HTTP header enrichment allows the operator to define a policy that inserts x-header fields
into HTTP POST or GET request packets to provide specific subscriber information such as
IMSI or MSISDN to the HTTP server without changing the protocol.

B.
HTTP header enrichment is the process that allows HTTP headers to be compressed for
optimal transfer across the network.

C.
HTTP header enrichment allows the operator to define a policy that detects the HTTP
packet that requires header enrichment. If a match occurs, the policy drops the packet,
modifies the packet inline with quality of service definitions, or creates a log message and
forwards the packet unmodified.

D.
HTTP header enrichment is the process in which a HTTP packet is analyzed for missing
or partial header fields. If missing fields are detected or incomplete, the Cisco ASR 5000 can
then take action to insert a new header, repair an existing header, create a log entry, and
forward the packet.
