updateListener method
- required String listenerArn,
- ClientAffinity? clientAffinity,
- List<
PortRange> ? portRanges, - Protocol? protocol,
Update a listener.
May throw InvalidArgumentException. May throw InvalidPortRangeException. May throw ListenerNotFoundException. May throw InternalServiceErrorException. May throw LimitExceededException.
Parameter listenerArn
:
The Amazon Resource Name (ARN) of the listener to update.
Parameter clientAffinity
:
Client affinity lets you direct all requests from a user to the same
endpoint, if you have stateful applications, regardless of the port and
protocol of the client request. Client affinity gives you control over
whether to always route each client to the same specific endpoint.
AWS Global Accelerator uses a consistent-flow hashing algorithm to choose
the optimal endpoint for a connection. If client affinity is
NONE
, Global Accelerator uses the "five-tuple" (5-tuple)
properties—source IP address, source port, destination IP address,
destination port, and protocol—to select the hash value, and then chooses
the best endpoint. However, with this setting, if someone uses different
ports to connect to Global Accelerator, their connections might not be
always routed to the same endpoint because the hash value changes.
If you want a given client to always be routed to the same endpoint, set
client affinity to SOURCE_IP
instead. When you use the
SOURCE_IP
setting, Global Accelerator uses the "two-tuple"
(2-tuple) properties— source (client) IP address and destination IP
address—to select the hash value.
The default value is NONE
.
Parameter portRanges
:
The updated list of port ranges for the connections from clients to the
accelerator.
Parameter protocol
:
The updated protocol for the connections from clients to the accelerator.
