A user has enabled session stickiness with ELB. The user does not want ELB to manage the
cookie; instead he wants the application to manage the cookie. What will happen when the server

instance, which is bound to a cookie, crashes?

A.
The response will have a cookie but stickiness will be deleted

B.
The session will not be sticky until a new cookie is inserted

C.
ELB will throw an error due to cookie unavailability

D.
The session will be sticky and ELB will route requests to another server as ELB keeps
replicating the
Cookie

Explanation:
With Elastic Load Balancer, if the admin has enabled a sticky session with application controlled
stickiness, the load balancer uses a special cookie generated by the application to associate the
session with the original server which handles the request. ELB follows the lifetime of the
application-generated cookie corresponding to the cookie name specified in the ELB policy
configuration. The load balancer only inserts a new stickiness cookie if the application response
includes a new application cookie. The load balancer stickiness cookie does not update with each
request. If the application cookie is explicitly removed or expires, the session stops being sticky
until a new application cookie is issued.
