-## Cors
-
-When the frontend of the application is not hosted by Jitar you want to enable cors on the web server. Jitar provides a cors middleware and in this example we demonstrate how to enable cors.

 ## Construction
 
 When starting and stopping a Jitar service, it might be useful to do additional tasks. In this example the use of start up and tear down scripts is demonstrated.

-## CORS
-
-Depending on the external application, CORS headers might be required to allow the connection. Jitar provides a CORS middleware implementation that you can use out-of-the-box.
-
-```ts
-// src/handleCors.ts
-import { CorsMiddleware } from 'jitar';
-
-const origin = 'https://example.com';
-const headers = 'X-Custom-Header-1, X-Custom-Header-2';
-const cors = new CorsMiddleware(origin, headers);
-
-export default cors;
-```
-
-This CORS handler needs to registered to a service in order to work. More information on this can be found in the [middleware](../develop/middleware#adding-middleware) section of the develop guide.
-
-Only a single origin is supported. If you need a multi-domain setup you can provide a * (wildcard). The allowed headers are specified in a comma-separated list. You can also use a * (wildcard) to allow all. By default the CORS middleware will use a wildcard for the domain and headers if not specified.
-
-The values for the allowed method are fixed to GET and POST, as these are the only methods the RPC API exposes.
