title: WebApp Content-Length Response Header
body: <p>GAS web app responses use chunked encoding (they seem to set the header Transfer-Encoding →chunked). But in my case I would need the Content-Length header instead.</p>
  
  <p>I know that from GAS we cannot change or set response headers, but anyone knows if through some setting, content type or deployment change this can be affected to use Content-Length header?</p>
