Configuring data exchange between clients and the CDN

When a client uses your service to request a file published via Cloud CDN, an HTTP or HTTPS connection is established between the client and the CDN load balancer, depending on the URI scheme: http://cdn.example.com/styles/common.css or https://cdn.example.com/styles/common.css.

Only a CDN resource with the Active status can distribute the content available to users. For more information, see Resource statuses.

For connections between clients and the CDN, you can configure:

• Client redirect from HTTP to HTTPS or vice versa as per this guide.

• certificates for HTTPS connections.

• HTTP headers in CDN server responses to clients as per this guide.

• CORS processing of cross-domain requests.

• HTTP methods allowed to clients in CDN requests as per this guide.

  By default, the POST, PUT, PATCH, and DELETE methods are not available in client requests. To find out whether you can use these methods, contact support. When contacting, describe your use case.

• Sending compressed content using the Content-Encoding: gzip HTTP header.
