Entering meta.discourse.org into onebox domains blacklist correctly prevents oneboxes of meta.discourse.org links. However, entering gulshankumar.net and www.gulshankumar.net into the setting does not prevent the oneboxing of https://www.gulshankumar.net/go/sucuri-website-firewall.
I appreciate your curiosity, why I wouldn’t like Onebox. The major issue is redirection which happens due to Onebox.
Basically, to keep affiliate URLs short, memorable and easily managed at one place, I use redirection. I use Affiliate Link Lite plugin to convert ugly affiliate link to the branded form.
@codinghorror I’m hitting this same basic issue on my forum, wondering if there’s yet any way to force the onebox blacklist to work on sibling domains please?
In my case I have forum.x.org and archive.x.org. The latter uses the forum as an sso provider to allow entry. When entering a url from the archive, it gets oneboxed, and the url gets redirected as far as a forum.x.org/session/sso_provider?sso=..... link, which if clicked on then results in an error page.
@codinghorror Ah, I’ve just checked something this morning, and it only seems to be doing it for links that had been oneboxed (with a bad redirected link) before I put the archive domain into the onebox blacklist. So there must be a onebox cache? Any idea how to remove links from that?
