Hi

Include the cookies from your webapp in the request to your backend. Then validate the cookie with Ory from your backend.
Some options:
1. Convert the cookie to a JWT (after it has been validated against Ory) for upstream validation with other backend services
2. Add a reverse proxy in-front of the entire backend which does the cookie validation with Ory per request.
Both options here can be done through Ory Oathkeeper, but it will mean hosting and managing another service.

Ory has a caching endpoint for the session check and is served on the edge, which means you should get sub 50ms per check.
