Hi,

How can we store session variables similar to PHP's $ \_SESSION for the HTTP Request component in NODE-RED? We have already managed to create and read the browser cookie, but we don't know how to create a variable that can be automatically destroyed when the session expires. We need to destroy the variable so as not to occupy server memory with closed sessions.

Tks
