Is there a way to pass request information, such as HOST header value, on to app.get?

My application requires that a particular host is present, so when I call it normally like this:

app.get(“foo”)

Specifically, I want to override the

request.env["HTTP_HOST"]

value.

    I’m not sure this help… I’ve seen code like the following:

    app.call({
      "HTTP_HOST"=>"...",
      "SCRIPT_NAME" => "",
      "PATH_INFO"=>"/lala/#{lala_id}/",
      "QUERY_STRING" => "",
      "SERVER_NAME" => "",
      "SERVER_PORT" => "80",
      "REQUEST_METHOD"=>"GET",
      "rack.input" => StringIO.new
    })
    

    You might be able to still use .get and just pass HTTP_HOST as an option like above?
