+ # The hosts that will be used to serve the app. The proxy will only route requests

+ # SSL
+ #
+ # kamal-proxy can provide automatic HTTPS for your application via Let's Encrypt.
+ #
+ # This requires that we are deploying to a one server and the host option is set.
+ # The host value must point to the server we are deploying to and port 443 must be
+ # open for the Let's Encrypt challenge to succeed.

+ #
+ # How long to wait for requests to complete before timing out, defaults to 30 seconds

+
+ # Healthcheck
+ #
+ # When deploying, the proxy will by default hit /up once every second until we hit
+ # the deploy timeout, with a 5 second timeout for each request.

+ # Whether to buffer request and response bodies in the proxy
+ #
+ # By default buffering is enabled with a max request body size of 1GB and no limit
+ # for response size.
+ #
+ # You can also set the memory limit for buffering, which defaults to 1MB, anything
+ # larger than that is written to disk.

+ # Logging
+ #
+ # Configure request logging for the proxy
+ # You can specify request and response headers to log.
+ # By default, Cache-Control, Last-Modified and User-Agent request headers are logged

+ - Cache-Control
+ - X-Forwarded-Proto

+ # If you are behind a trusted proxy, you can set this to true to forward the headers.
