+CORS (Cross-origin resource sharing) describes which address or origins can access the REST API from the browser.
+By default, sharing resources cross-origin is not allowed.
+
+A wildcard, single origin, or multiple origins can be specified as part of the `cors_allow_origins` parameter:
+
+
+Example of a REST configuration:
+
+```yaml
+
+rest:
+  listen_port: 1789

+    x-header-1: header-value-1
+    x-header-2: header-value-2
