title: HTTP vs HTTPS requests with Retrofit
body: <p>I'm working on REST API client for Android using Retrofit.
  Some of the use something like this <code>http://my.backend.com</code> and others use <code>https://my.backend.com</code>. The way I found is to create two separate interfaces and build two RestAdapters with different endpoints.
  But I would like to keep my interfaces consitent and I'm wondering if it is possible for example build my Res adapter with <code>my.backend.com</code> and specify if the methot thould use https with <code>@HTTPS</code> annotation ?
  Thanks.</p>
