Istio come with out of the box ability to validate the JWT tokens that comes inside a client request header. And we were able to sucessfully use the RequestAuthentication policy.
- Validate the JWT token inside the request header
- Forward request with valid JWT to application code
- Deny traffic with invalid JWT
My query was if we can cache the JWT tokens at the ingress gateway for improved performance. Can you provide some pointers on how this can be done.
