This question already has an answer here:
I have created a landing page using HTML/CSS/JS which will be at
The home site is built in WordPress,
www.example.com. I want only the home page of
www.example.com to redirect to this landing page
www.example.com/welcome, not the entire site, so no 301 redirect. In my research I have found that adding this code to your htaccess will redirect your home page only, is that correct?
RedirectMatch ^/$ http://www.example.com/welcome
