Redirect 301 with htaccess options?

Question

htaccess

Good afternoon!
Please tell me how to correctly make redirect 301 with parameters.
For example, site1.ru/?id=1&val=2, when you go to such an address, redirect 301 to such
site2.ru/?id=1&val=2 should work
. Many thanks in advance!

Answer 1

RewriteEngine on
RewriteRule ^ http://site2.ru [R=301]

Or:

RewriteEngine on
RewriteCond %{QUERY_STRING} id=1&val=2
RewriteRule ^ http://site2.ru [R=301]

Or

RewriteEngine on
RewriteCond %{QUERY_STRING} ^id=\d+&val=\d+$
RewriteRule ^ http://site2.ru [R=301]
