HTACCESS 301 redirect issue with strange url variables

Question

google webmaster tool is notifying me a 404 error about the following url:

http://www.giobby.com/&force=1

I added the following rule to htaccess file, but it doesn't work:

RewriteCond %{QUERY_STRING} ^&force=1
RewriteRule ^/?$ http://www.giobby.com/? [L,NC,R=301]

Can someone suggest me the correct rules?

Answer 1

Try just:

RewriteRule ^&force= / [L,NC,R=301]
