Apache rewrite rule that matches a specific query string

Question

I need to rewrite a specific WordPress URL to a 404 error:

?page_id=15 to 404

How can I match the query string? Apparently Apache doesn't feed that to the rewrite mod...

Answer 1

Using mod_rewrite, you can match a query string using this:

RewriteCond %{QUERY_STRING} page_id=15
RewriteRule .* - [R=404]
