Is it possible to redirect all parent links to another single page?

Please see https://redirection.me/support/redirect-regular-expressions/

Hey John, thanks for the quick answer.
I have seen that, and tried to go by the instructions but it’s not working for me, maybe I’m doing something wrong, but there it’s speaking about variables changing after the /
I have variables change after =
I have done the same like the instructions there:

/?fbclid=.*

And I have also picked the regex.

But it’s not redirecting, it’s just add the new url to the current one.

Maybe I’m doing something wrong?

The regular expression should look at the whole URL, not just the end part. Also ? is a regular expression character and will need to be escaped as \?

You can use https://regex101.com to test your expression

I have changed the / to \
Now its redirecting but in a wrong way…
Its redirect to:

https://example.com/https:/example.com/XXXXX

and im getting an 404 error

No, it’s the ? that should be changed to \?

You appear to have put an invalid URL as the target.
