Hi Team,

We have setup a Nginx Server for token authentication using secure_link_md5 Module as per below link
http://nginx.org/en/docs/http/ngx_http_secure_link_module.html

Please let me know how to proceed for two secret keys, say primary secret key and backup secret key so that if we are changing the primary key the current requests should get authenticated from backup key, provided we have copied the same key(i.e. primary key before changing) in backup key.

Regards,
Anish
