URL Rewriting in Wordpress htaccess

Question

I've built a Wordpress site that has a product page which retrieves product info from an external system using the querystring id passed in. So www.domain.com/product/?id=n loads the Wordpress product page which then loads the product info using the id.

This works fine.

However, I want to rewrite this URL so that:

www.domain.com/product/productname/id retrieves www.domain.com/product/?id=n

When I add the following to htaccess, the page returns a 404 because it doesn't exist in Wordpress.

RewriteRule ^product/productname/(.*)$ ^product/?id=$1 [L]

Does anyone know how to write this rule in such a way that it doesn't get hijacked by Wordpress rewriting?

After doing some additional searching, I've found some links that may help you get started. The secret lies in WordPress's add_rewrite_rules hook. Haven't tried these myself yet, but looks promising:

• http://codex.wordpress.org/Rewrite_API/add_rewrite_rule
• URL rewriting via Wordpress Rewrite or .htaccess
