.htaccess redirect url excluding certain subdirectories - apache

Question

I'm trying to redirect my WordPress multisite root site to another page, but I still want to be able to access /wp-admin, /wp-login and /wp-json.
When I go to the browser I want url.com to redirect to newurl.com UNLESS it has one of the above directories on the end.
This is what I've come up with but when I go to the browser and enter url.com it loads the page as usual. Where am I going wrong?
Note: The block at the bottom is where the redirect should be happening.

Answer 1

Your rule was working fine.
You did not see it because it was never reached due to its position in the htaccess.
Actually, you need to place your rule before the default-last rule, otherwise it won't never be executed.

This works just fine for me. I changed a few things on the condition and added, the L flag to make sure it stops when the rule is met. Make sure your .htaccess file is being read. You can verify your apache config file has AllowOverride All or it won't read your htaccess file.
