I've recently changed my URLs with parameters to more readable URLs with the following *.htaccess*:

```
RewriteRule ^page/([A-Za-z0-9-+_\s]+)$ /index.php?n=$1 [L]
RewriteRule ^category/([A-Za-z0-9-+_\s]+)/([0-9]+)$ /index.php?p=$1&b=$2 [L]

```

I believe this poses problems now with duplicate content on the search engines, as `index.php` URLs and `domain.com/page/` URLs will both be indexed.

If calls made to `domain.com/page/1` get redirected to `index.php?n=1` how can I redirect requests made to `index.php` to `domain.com/page/` ?

My attempt to do so is giving me a 404 code sending me to domain2.

```
#RewriteCond %{QUERY_STRING} ^n=([A-Za-z0-9]+)$ [NC]
#RewriteRule ^index\.php$ http://domain.com/page/? [R=301,L]

```

**.htaccess:**

```
