I want to remove some of the headers that the [fly.io](http://fly.io) proxy sends.

I want to remove:

- the ‘via’ header
- the ‘server’ header
- the ‘fly-request-id’ header
- and the ‘x-powered-by’ header

According to this [thread](https://community.fly.io/t/new-feature-basic-http-response-header-modification/3594) that would be possible by adding a simple line to the fly.toml file:

```auto
...
[[services.ports]]
    ...
    http_options = { response = { headers = { via = false, x-powered-by = false, server = false, fly-request-id = false } } }
...

```

But if I deploy this fly.toml file nothing happens. The headers are still send from the [fly.io](http://fly.io) proxy.

Could be a weird toml thing, I’ve had success with this format (watch your white space)

```toml
  [services.ports.http_options.response.headers]
    Via = false
    X-Powered-By = false

```

(I’m not sure if the Fly Proxy ignores this setting for certain headers, such as the request ID - someone can hopefully answer that if it becomes an issue).

Make sure you’re running a `fly deploy` after making any changes here.

This may not be implemented properly for machine apps yet.

Thanks for your answers!

I will definitely take a look at @fideloper-fly‘s solution and hope I will have success with it.

I will answer to this topic what my results were.

I would definitely appreciate if [fly.io](http://fly.io) would implement that to work with all headers.

Thanks!

Have a nice day!
