Does NLB support tls session resumption?

0
openssl s_client -reconnect -tls1_2 mywebsite.com:443

mywebsite.com is resolved to the NLB. I used this command to test, and found that the tls session was never reused.

If i use ALB, the session is reused.

Anyone can tell me what is wrong?

Hi,

Session resumption is fully detailled here: https://repost.aws/knowledge-center/elb-ssl-tls-session-resumption-support

Network Load Balancers

Network Load Balancers support only session tickets for session resumption. 
Resumption using session tickets is supported at the Regional level. Clients can
 resume TLS sessions with a Network Load Balancer using any of its IP addresses.

Best,

Didier
