http-only site to test REST requests?

After the latest move by httpbin to HTTPS, apparently all sites that accepted test REST requests have disappeared. I've checked all mentioned in this post, and either they do not allow all kind of requests, or have also moved to HTTPS. For Raku modules such as this one, LWP::Simple, we need a HTTP-only site due to problems with certain operating systems. So is there any site left or will we have to roll out our own server?

How do I test HTTP requests?

Here are some tips for testing POST requests: Create a resource with a POST request and ensure a 200 status code is returned. Next, make a GET request for that resource, and ensure the data was saved correctly. Add tests that ensure POST requests fail with incorrect or ill-formatted data.

You can use http://eu.httpbin.org. This URL doesn't redirect http to https.
