Get the final destination after WP_Http redirects (WordPress)

I’m doing some requests to an API via WordPress, and the API uses SSL connections if they’re turned on in the API settings. I’d like to determine whether SSL is turned on or off without having to ask the user if SSL is turned on on their account, and the API does a good job at redirecting, meaning

• If I access http://api/endpoint and SSL is turned on, I’m redirected to https://api/endpoint
• If I access https://api/endpoint and SSL is turned off, I’m redirected to http://api/endpoint

Now what I’d like to do is see whether a redirect happened or not and record that to my options so that the other requests are fired to the correct URL without any redirections.

So my question is: is there a way to determine the final destination after firing a WP_Http->request() when the request is being redirected?

I can’t see any info about that in the response arrays, I only get to see the final response but I have no idea what URL that came from. What I can do is set the redirection parameter to 0 and catch the max redirects allowed error, but that’s not bullet-proof, since I still don’t know whether the redirect happened from http to https or simply another page under http.

I hope this all makes sense, let me know if you have any ideas.

Thanks!

You can use wp_remote_head() request for a test, it should get you response code and redirect target.
