How to redirect - server is ATS/3.1.1-unstable

I came across this on another thread:

If you have a list of URIs that need redirected, I would recommend that you ask your host to allow a RewriteMap for those. When they refuse (because you can bring down the whole server), then use PHP header() redirections within those scripts (if strictly HTML, use the <meta http-equiv=“refresh” content=“0; url={new URL}”>). To do otherwise, as explained above, is an abuse of the server and SHOULD have you barred from hosting on a shared server.

Does this mean I can re-instate the “dead” pages without any content and just add <meta http-equiv=“refresh” content=“0; url={new URL}”> in the header to achieve the re-direct? Do I need to use a full URL or can I just use the new page?
