I am trying to pass pem-encoded client certificate to proxied service via a X-SSL-Cert header, like so:

sub.example.com {
    reverse_proxy 127.0.0.1:8000 {
        header_up X-SSL-Cert {http.request.tls.client.certificate_pem}
    }

    tls {
        client_auth {
            mode require
        }
    }
}

However, if you execute ngx.exit during the access phase, it only interrupts the request processing phase, and the response phase will still process it, i.e. if

Is your feature request related to a problem? Please describe.

As observed during #261, users can accidentally set timeouts inconsistently. A concrete example is that one can set a User facing timeout lower than any backend timeout, such that requests may fail early.

Describe the solution you'd like

We should provide some sanity checking to prevent unintended timeout behavior.

currently "option forwardfor" cant't be unset, so there is no way to enable it in the default section and disable it in a particular frontend

It would be nice to have a validation every time ergo runs in order to avoid badly formatted files and undefined errors.
