We have a client that is closing its doors. We want to redirect all traffic that goes to their domain to a new page index.html with a few images in the _img subdirectory. (The page explains what happened, what current customers can expect with their current orders, etc.)
I've read about possibly using HTTP 410 Gone as the best way to technically explain to bots, etc. that the site is not there, isn't coming back and isn't providing a forwarding address. What would be the best way to do this in an .htaccess file, and direct users to the new index.html?
