What will happen when the server instance, which is bound to a cookie, crashes?

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

Answer: B

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.
