How to make a redirect from all GET requests for the main page to itself without parameters?

Question

htaccess

Good day, colleagues! Help me solve a problem that I couldn’t solve with my narrow brain ...
You need to make a 301 redirect to www (both with www and without www) on the main page,
if after the slash http://(www.)site.ru/ there is a sign ?
Those. it is necessary if a request with a GET parameter goes to the main one - it’s easy to redirect to the main one

Answer 1

I answer my own question:

RewriteCond %{THE_REQUEST} " /\?"
RewriteRule ^ /? [R=301,L]

RewriteCond %{THE_REQUEST} " /\?"
RewriteRule ^  http://www.site.ru/? [R=301,L]

The first option does not change the domain
site.ru/? => site.ru
www.site.ru/? => www.site.ru
The second option always sends to the domain from www
site.ru/? => www.site.ru
www.site.ru/? => www.site.ru
