CorsEnabledServiceHelper (Helidon Project 2.6.9 API)

java.lang.Object
- io.helidon.webserver.cors.CorsEnabledServiceHelper

```
public class CorsEnabledServiceHelper
extends Object
```
Allows services (including Helidon built-in services) to register CORS support easily.
Callers use either create(String) or create(String, CrossOriginConfig) to initialize the helper for a service. The helper uses the CrossOriginConfig instance to set up CORS behavior for the service. If the caller passes a null CrossOriginConfig or invokes the other variant of create then the sets up CORS using a default configuration:
```
     enabled: true
     allow-origins: ["*"]
     allow-methods: ["GET", "HEAD", "OPTIONS"]
     allow-headers: ["*"]
     allow-credentials: false
     max-age: 3600
     
```
All of those settings except for allow-methods are the defaults for CrossOriginConfig.
