title: How do i specify spray Content-Type response header?
body: <p>I understand that spray does that for me, but I still want to override it with my header, how can I override the header in the response?</p>
  
  <p>My response looks like this:</p>
  
  <pre><code>case HttpRequest(GET, Uri.Path("/something"), _, _, _) =&gt;
    sender ! HttpResponse(entity = """{ "key": "value" }""" // here i want to specify also response header i would like to explicitly set it and not get it implicitly
  </code></pre>
