title: Zuul - hitting a https resource
body: <p>I am trying to a hit a service that is registered with Eureka. Obviously, my zuul project is also registered with Eureka. I am not sure what am I doing wrong but if someone can point me in the right direction that would be great. I thought setting ribbon.IsSecure=true would fix it but for some reason, nothing seems to work.</p>
