Stop .htaccess from caching

Question

My old .htaccess which redirected my website to www.domain.com . However, now I want to change my .htaccess to something else (which I did), but my website still gets redirected to www.domain.com . If I go into incognito mode the new .htaccess works. How to I make it so the old .htaccess cache is cleared on my visitors computers.

I had a look at htaccess file somehow being cached? but I honestly don't understand this because I tried adding -MultiViews to my .htaccess.

My new .htaccess looks like this. My goal being all URL's get redirected to home page. No matter what URL you type it goes to the homepage.

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/index.php$
RewriteRule .*\.(php|html)$ /index.php [L,R=302]
-MultiViews

Answer 1

RewriteEngine On 
Redirect 301  /index.php
