EdgeRules can be configured to redirect a client based on the User-Agent sent with the request. We will look at an example of this here.
The EdgeRules feature is available only on Enterprise plans.
Example: Redirecting by User-Agent
Some user agents (web browsers) act differently than others. In this example we will show you how to create a redirect if the end user is using a iPhone or Android smartphone.
