HttpServer.Response
Build up a response as a command.
Usually this will look something like this,
in your update function,
assuming you subscribed with a GotRequest msg:
GotRequest req res ->
    { model = model
    , command =
        res
            |> Response.setHeader "Content-type" "text/html"
            |> Response.setBody ("<html>Hello there!</html>")
            |> Response.send
    }
            
                type Response 
            
            
                
        An HTTP response.
            
                send :
                	Response -> Cmd a            
            
                
        Command to send an HTTP response.
            
                setBody :
                	String -> Response -> Response            
            
                
        Alias for setBodyAsString.
            
                setBodyAsBytes :
                	Bytes -> Response -> Response            
            
                
        Set the body of the response to some bytes.
            
                setBodyAsString :
                	String -> Response -> Response            
            
                
        Set the body of the response to a string.
            
                setHeader :
                	String -> String -> Response -> Response            
            
                
        Add a header key/value pair to a response.
            
                setStatus :
                	Int -> Response -> Response            
            
                
    Set the HTTP status code on a response.
