I moved my site and I want to use the old site. The best way to use both is to show the current pages, if there is no page, redirect to the same address on the new site.
Can I do this only from the .htaccess file from old site?
If I can't do this, I think of another way to come. I can redirect 404 pages to the 404.php file on the new site. Can I then redirect the same URL using http_referer with the 404.php file?
