How to remove spray-can/1.3.3 from response

Question

I use spray.io to serve HTTP requests. In response there is information about spray framework that I would like to remove. So how to remove "Server: spray-can/1.3.3" from the response header in spray?

Answer 1

You can set this via application.conf:

spray.can {

  server {
    # The value of the `Server` header to produce.
    # Set to the empty string to disable rendering of the server header.
    server-header = spray-can/${spray.version}
  }
}
