You can configure URL redirection to forcibly redirect HTTP requests from a client to a point of presence (POP) to HTTPS for greater security.
Use cases
For an accelerated domain name that is configured with an SSL certificate, you can configure URL redirection. By default, this feature uses a 301 redirect to force HTTP requests from clients to the CDN node to be redirected to HTTPS. HTTPS requests are more secure.
