By default, Edge Security Acceleration (ESA) points of presence (POPs) retrieve content from origin servers using the same protocol as the client. You can create origin rules to configure different protocols and ports, and apply the rules to origin requests that have different characteristics.
Create an origin protocol rule
In the ESA console, choose Websites and click the website name you want to manage.
In the left-side navigation pane, choose .
Click Create Rule, and fill in the Rule Name.
In the If Requests Match... area, specify the conditions for matching incoming requests. For more information about how to configure a rule, see Rules.
Click Configure in the Origin Protocol and Port section. Then, select an origin protocol and set the HTTP and HTTPS port numbers.
Click OK.
