How to make a redirect (go) in .htaccess to another site?

Question

PHP

Tell me, please, how to do a redirect?
I do it like this

RewriteRule ^go/(.*) http://$1 [R=302,NC,L]
<a href="/go/https://www.change.org/ru/"></a>

,
but I would like it to pass from all cases

<a href="/go/https://www.change.org/ru/"></a>
<a href="/go/change.org/ru/"></a>
<a href="/go/http://change.org/ru/"></a>

but it goes like this https/www.change.org/ru/, that is, somehow you need to take into account the protocol (%{THE_REQUEST})
How to make a redirect so that it works with the protocol (http or https) and without it?
