By default, a CDN server passes all HTTP headers it receives from the client's origin to end-users.
To adjust the headers that are being passed, in the resource settings find and enable the Response headers (hide) option.
After enabling the list of the most popular headers will appear in the field:
- HTTP
- Server
- Date
- Content-Type
- Content-Length
- Connection
- Vary
- Last-modified
- Connection
- Accept-range
- Content-encoding
- Etag
- Cache-control
- Expires
- Keep-alive
- Accept-range
To delete the header press ×.
You can also add your custom headers. The new header can contain such characters as letters (a-z), numbers (0-9), dashes (-), underscores (_). If the header is added correctly, it will appear in the orange square.
These are default headers which can't be hidden:
- HTTP
- Server
- Date
- Content-Type
- Content-Length
- Connection
