v1.11.0

1.11.0

With this release Couper brings even more value when it comes to connecting services and security. We made mTLS configurable for both sides, the server side and the backend one. Couper is normally used behind an ingress but is now able to serve secured content and forces clients to present a valid certificate if configured. For the backend blocks Couper acts as client and is able to present a client certificate to the origin. This feature also allows to additionally configure a CA certificate per backend, unlike the ca_file option which configures a certificate for all outgoing connections.

To configure a Single Page Application for different environments, believe it or not, things could get complicated. Couper comes with a simple but powerful spa attribute to inject a custom JSON object into the bootstrap file via a defined placeholder while serving this to the client.
