Configure the forcible redirect feature

If SSL certificates are configured for NGINX, you must force Dynamic Route for CDN (DCDN) to redirect HTTP requests to the HTTPS versions of web pages. You can configure the forcible redirect feature to specify requests from clients to edge nodes as HTTP or HTTPS requests based on your business requirements. This topic describes how to configure the forcible redirect feature.

2. In the left-side navigation pane, click Domain Names.
3. On the Domain Names page, find the domain name that you want to manage, and click Configure in the Actions column.
4. In the left-side navigation pane on the details page of the specified domain, click HTTPS Settings.
5. In the Force Redirect section, click Modify.
6. In the Force Redirect dialog box, select a Redirect Type.
