Question

How can I redirect all external links (ie clicks from Google towards my site) from product.php?id=1&cat=2&show=3 to new_product.php?id=1&cat=2&show=3 ?

The reason is, product.php is used only in a colorbox window without header/footer/menus etc for users that already on the website. If someone is linking directly to this page from, let’s say Google results, they’re getting an incomplete layout, whereas new_product.php has the full layout.

Did you try something like this?

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yourdomain.com/.*$ [NC]

and now the rule like:

RewriteRule ^product.php? http://yourdomain.com/new_product.php? [L,QSA,R=301]
