Overview

The Client Byte Range Request rule allows for enabling or disabling client byte range requests for a particular host or path. Range request support is enabled by default. When Client Byte Range Request is disabled, the “Content-Range” header in client requests to the CDN is ignored and the complete file is delivered to the client.

Configure the Rule

Here, we'll describe how to configure the rule with the Delivery Service Management UI.

API Users may choose to build the site configuration offline.

To configure a Byte Range Request rule:

  1. Navigate to the Select Rule dialog.

  2. In the Select Rule dialog, choose Client Byte Range Request.

  3. Toggle Client Byte Range Requests on or off.

SVTA Component: QW.HttpRangeRequests

When you save the configuration version, the QW.HttpRangeRequests component is added to the JSON configuration. This is a private feature developed by Qwilt.

In this example, the QW.HttpRangeRequests SVTA component is configured to disable Client Byte Range Requests.

{
  "generic-metadata-type": "MI.PrivateFeature.Qwilt.QW.HttpRangeRequests",
  "generic-metadata-value": {
    "enable": false
