OAuth Introspection : Does the plugin ask validation every time?

Hi all,

I have a simple questions about the OAuth introspection Plugin. I would like to know if every time a request is processed by kong and the plugin, does the plugin verify the token by sending a request to then introspection endpoints or use the expiration date of the token, it might have stored, from previous requests.

Couldn’t find that info anywhere.

Thanks for the answers
