Stealth Worker developer here, I coded a javascript redirection from http to https like this: <a href="http:&#x2F;&#x2F;stackoverflow.com&#x2F;a&#x2F;4723302" rel="nofollow">http:&#x2F;&#x2F;stackoverflow.com&#x2F;a&#x2F;4723302</a>. What you are seeing may be the result of a slow transition from http to https. I apologize for any inconvenience (but please only use the https version of our website!).
