render xml

I’m trying to respond xml for any action in my controller but not just by rendering an object I wanna use a view and all the examples I find show how to respond xml with an object like respond_with(@asd) # respond_with A or format.xml { render xml: @asd}

class SitemapController < ApplicationController

layout :false

respond_to :xml

def index

@host = “#{request.protocol}#{}”

@people = Person.order(“name”)

@pictures = Picture.all




Since google says my sitemap.xml is unknown type it must be I’m rendering xml but not seending an xml content/type header first So how do I send the header?
