How HTACCESS redirect using URL nid number range

Recent, i have problem

I want redirect on range id content to a subdomain.

For example:

From id = 501 to 1000 i want redirect to a subdomain

oldcontent1.example.com

My url on domain: http://example.com/article/123

My url on subdomain: http://oldcontent.example.com/article/123
