How to redirect from one page to another using .htaccess?

Question

htaccess

Hello dear gentlemen!
How to make it so that if a person visits a link like: www.mysite.ru/test.aspx the .htaccess file would redirect him to the same html page ( www.mysite.ru/test.html)
There is a .htaccess code:

RewriteCond %{REQUEST_URI} ^/test.aspx$
RewriteRule ^.*$ http://mysite.ru/test.html? [R=301,L]

I don't understand what's wrong?

Answer 1

RewriteCond %{REQUEST_URI} ^(.*)\.aspx$
RewriteRule ^.*$ http://mysite.ru/%1.html? [R=301,L]

If group is in RewriteRule then each parenthesis is $1$2 and so on
If parenthesis is in RewriteCond then %1 %2

Answer 2

Found another way:
Redirect 301 /test.aspx http://mysite.ru/test/
