How do I redirect a non-existent htaccess url?

Question

I need to redirect the following link:

http://dominio.com/receitas-user/ID_do_usuario/nome_do_usuario

To:

http://dominio.com/receitas/author/nome_do_usuario

Being nome_do_usuario and ID_do_usuario two variables.

I tried to do it this way but it didn’t work:

RewriteCond %{QUERY_STRING} !=""
RewriteCond %{QUERY_STRING} ^/receitas-user/([0-9-a-z\-]+)/([0-9-a-z\-]+)$ [NC]
RewriteRule ^(.*)$ http://dominio.com/receitas/author/%2? [R=301,L]

Answer 1

It seems that this is wrong %2. The match should be with dollar, so $2

Should stay like this:

RewriteCond %{QUERY_STRING} !=""
RewriteCond %{QUERY_STRING} ^/receitas-user/([0-9-a-z\-]+)/([0-9-a-z\-]+)$ [NC]
RewriteRule ^(.*)$ http://dominio.com/receitas/author/$2? [R=301,L]
