This function allows you to set the HTTP response header. Currently, nine HTTP response header parameters are available. The following table describes these parameters.
| Parameter | Description |
|---|---|
| Content-Type | Specifies the content type of the response returned to the client. |
| Cache-Control | Specifies the cache mechanism for the requests from and responses to the client. |
| Content-Disposition | Specifies the name of the default file to be activated in the file download settings when the response is returned to the client. |
| Content-Language | Specifies the language of the response returned to the client. |
| Expires | Specifies the expiration time of the response returned to the client. |
| Access-Control-Allow-Origin | Specifies the allowed CORS request sources. |

| Access-Control-Expose-Headers | Specifies the allowed custom header information. |
Notes
- The HTTP response header setting affects the responses returned to clients (for example, browsers) for all resources under the CDN domain. However, it does not affect the actions of the cache server.
- Currently, only the preceding HTTP header parameters are supported. If you require more HTTP header settings, submit a ticket.
- The Access-Control-Allow-Origin parameter can be set to a wildcard (*) (which indicates all domain names) or a full domain name, such as example.com. Currently, wildcard domain names are not supported.
Procedure
