Small "hic" with a 301 htaccess redirect
===

i would like simply to create a 301 redirect, but my code does'nt work and returns a beautiful 404 page (-_-).

I think the problem is the "?" in the from url, i tried to escape it but it doesn't work anymore.

    RewriteRule ^produit.php?PDT_ID=473 /product.php?id_product=210 [R=301]

Thanks to take a look
