We had an old mobile site hosted by a 3rd party that has since been deleted. We've been advised to put in 301 redirects for specific pages from the old mobile site to the new mobile site. How do you do this on a site that has been deleted already? I know this can be done in IIS, web.config and at the page level but if it no longer exists, I'm not sure how to do it or is it even possible? Also, we have control over the old domain.
