httputil proxy integrity errors on serving hugo/nginx files

[Sankar]

I have a Go proxy server which will proxy the incoming requests to a different nginx service, where a bunch of static files generated from hugo are deployed. The Go proxy server code is:

```

func (w http.ResponseWriter, r *http.Request) {

    proxy := httputil.NewSingleHostReverseProxy(target)

    proxy.Transport = debug.Transport{} // Set some Debug TCP options here

    proxy.ServeHTTP(w, r)

}

```

The debug.Transport is created like below:

```

type Transport struct {

    Transport http.RoundTripper

}

func (d Transport) RoundTrip(r *http.Request) (*http.Response, error) {

    fmt.Println(r.Header)

    d.Transport = &http.Transport{

        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},

    }

    return d.Transport.RoundTrip(r)

}

```

In the debug Transport, I am already ignoring the certificate checks for TLS configuration.

If I directly access the nginx url where hugo static files are served, then the static files are perfectly loaded. The static files are served fine even if I access from an nginx-ingress in addition to the nginx. However, when the requests are served via the Go proxy, then I get an error in my browser:

```

Failed to find a valid digest in the 'integrity' attribute for resource 'https://<blah>/js/main.min.29b0315468c00226fa6f4556a9cebc0ac4fe1ce1457a01b22c0a06b329877383.js' with computed SHA-256 integrity 'Nk/s9htIgKJ5jeLFxUMWgIQGhxGZBKoEWtWEy2qYtJk='. The resource has been blocked.

```

Any idea how I can skip this integerity check in the Go http proxy ? I cannot find any TLS Config option for it.

Thanks.
