1. Create a site
2. Set up local Staging
3. Add virtual hosts in the site configuration menu for the Public Pages "live.test.com" and the Staging Public Pages "dev.test.com"
4. Add both of them to your Hosts file
5. Add a new Public page
6. Select the configuration of the Public Pages. Your robots.txt should have the following:

   User-Agent: *
    Disallow:
    Sitemap: [http://dev.test.com:8080/sitemap.xml]
   

7. Replace Disallow: to Disallow:/testing in the textarea of robots.txt
8. Publish the page to live

Expected behavior: Possibility to configure the output of the robots.txt sitemap host

Actual behavior: The live site's Robots.txt will be overwritten by the staging version
