New to coding, unsure how to deal with conditional redirects

[ad_1]

I am new to coding and I’m trying to set up my htaccess file with conditional redirects. So that if the page it’s redirecting to turns up a 404 error, it will automatically redirect to another page that is up and live

Here’s the code I had generated, but I’m not sure if it’s right. I’m missing or where I could even find the code pre-made?

RewriteEngine On

RewriteCond %{HTTP\_HOST} \^example.com$

RewriteCond %{REQUEST\_URI} \^/old-url$

RewriteRule \^(.\*)$ \[R=301,L\] [ad_2]
