My site and all it resourced serving with https, nginx redirect all http request to https. When using OpenGraph meta, do I need to duplicate all resources with :secure_url? For example,
<meta property="og:url" content="http://example.com">
<meta property="og:url:secure_url" content="https://example.com">
Or it's enough to specify only one property (but which one - with secure or not) and https resource?
