Kvarn’s reverse proxy implementation allows pass through of web servers’ responses.

On the git version of Kvarn, URL rewrite is implemented, and automatically applied.

It can for instance pass all requests under /api/* to a backend server. It caches according to the cache-control and kvarn-cache-control headers. /api/search?q=icelk becomes a request to /search?q=icelk on the backend server.

This implementation is used by me for proxying my self-hosted Bitwarden vault (using Vaultwarden, of course) to the internet.


You start with constructing a manager. I recommend using static_connection and localhost and the Manager::base constructor.

Consider Manager::new for more control.

Then, mount it to your extensions using Manager::mount.
