Since we're only dealing with HTTP(S), something like this would be less
ambiguous: request.url.matches("^http?s://")

Why are we? It's universal, it rewrites:
GET /file.name
into:
GET http://host/file.name
It should not do any rewriting in case it will find any schema in URL. I do not
see any reason to break this universalism.

+    {
+      request.url = "http://" + request.headers.get("host") + request.url;
+    }
+    return false;
+  }
