Thanks for the replies, y’all - I’m not managing that Discourse instance any more and we no longer “need” this functionality, but it’d be nice to know it’s there.
@tshenry it seems to me that your example is what was discussed above as an “external” link, though, right? Taking a request from an external source and redirecting it to the proper Discourse URL - what we were hoping to do would be akin to redirecting Support - Discourse Meta to Issues · discourse/discourse · GitHub (if you all accepted issue reports there, of course), which worked (as I recall) for folks coming into the site from outside, but failed to redirect on the first page load when following a link from a Discourse page.
