I have a blog that sit in subdomain. = www.blog.com/sub and i want to move it to www.blog.com. so the only things that would change is filepath for every article will lose sub in its link right ? = www.blog.com/sub/article to www.blog.com/article how can i rewrite or redirect it so that when someone click to a link www.blog.com/sub/article1 it will auto drop /sub and goes to the new place where the article sits ?
