Using htaccess for wordpress attachment URLs

Question

We appear to have an issue with a bunch of old-style wordpress URLs, for example:

http://example.com/?attachment_id=11894

Which don't exist.

I'd like them to drop out of the index entirely, so I'd like to serve a 410 GONE status, ideally with .htaccess is there a RewriteRule or similar pattern I can use to get rid of them for once and all?

Answer 1

RewriteCond %{QUERY_STRING} (^|&)attachment_id= [NC]
RewriteRule / - [G]
