This is the story. I once had a host that allowed a static IP, but now it doesn't. When I had an exclusive IP number I had set a subdomain, there was where Google & Co. looked at.
But now, without static IP, I want to know no more of subdomains. It was the wrong approach to my needs too, so no condolences please. The stuff that used to be at the subdomain is now on its own directory.
My question is: how do I set a "410 - gone" to the subdomain? It can be done at .htaccess with "Redirect gone /im_not_here", but im_not_here is (no more) in the root directory, and I want the world to forget the subdomain, that doesn't look to be inside.
As a related point, the 410 status code is, as far as I know, supported only on HTTP/1.1; would googlebot understand it?
(I lied about the video; that was the lie)
