NucleusRedirect (HttpContext context, String location)

Return a custom "Nucleus redirect" response. We use the X-Location header rather than location because browsers automatically follow regular redirects, and when we do a POST using jQuery.ajax we want to handle these as a full page redirect, rather than what the browser would do, which is replace the AJAX response with the contents of the redirect location url. Nucleus redirects are handled in nucleus-shared.js.
