*Note:* If you rate-limit requests by using the `delay` parameter you have to make sure that the time between two refreshes is larger than the time needed for one refresh cycle.
**Attention:** `baseUrl` (and `stateExtension`/`commandExtension`) should not use escaping (e.g. `%22` instead of `"` or `%2c` instead of `,`).
URLs are properly escaped by the binding itself before the request is sent.
Using escaped strings in URL parameters may lead to problems with the formatting (see below).
