Various problems with http_get and http_post. They have been failing partly because the world has moved to HTTPS and these routines do not know how to handle that and certain files this would access is not available on the server.
In particular http://test.openeuphoria.org/post_test.ex gives a 302, which redirects to https://openeuphoria.org/post_test.ex which gives me a 404. And in a similar way http://test.openeuphoria.org/post_test.txt fails as well.
It seems to me, these routines should both rely on libcurl in both the Windows and Linux implementations.
I will commit a new branch for this later and import it into the openeuphoria repo
