// PodPortForwardOptions is the query options to a Pod's port forward call
// when using WebSockets.
// The `port` query parameter must specify the port or
// ports (comma separated) to forward over.
// Port forwarding over SPDY does not use these options. It requires the port
// to be passed in the `port` header as part of request.

In the end, [after evaluation](https://docs.google.com/document/d/1c2123cKuYsBDpIon9FFdctWTUIMFweSjgwG7r8l3818/edit), the decision was to move forward with a Rust implementation.
This offered performance benefits that were too large to leave on the table, as well as opportunities to tune to our specific needs.

## Configuration protocol

upon discussion in the [ztunnel hairpinning doc](https://docs.google.com/document/d/1uM1c3zzoehiijh1ZpZuJ1-SzuVVupenv8r5yuCaFshs/edit#heading=h.dwbqvwmg6ud3))

When a ztunnel receives traffic (authenticated or not) from a workload, it will forward that traffic to the Waypoint proxy **after** applying any `TRANSPORT` layer policies (i.e. `Authorization`s). Thus, if the destination workload has at least the equivalent of a `STRICT` `PeerAuthentication`, unauthenticated traffic will be rejected...
