I've read that nonces are meant to be for one time use only, and after an ajax request, you should issue a new nonce so with the next ajax request, a new nonce would be sent to the server.
However, I just tested repeated ajax requests using the same nonce token, and for each request
wp_verify_nonce returned true on the same token, meaning it could be reused dozens of times.
Is this intentional, or a bug?
Do I still need to issue new nonces with each ajax request, or can the same one continue to work for all future requests?
