The Default Rule applies to all requests for your Ion property. It includes some specific behaviors you need to configure.

Set up the Origin Server

An origin server is a physical location that ​Akamai​ uses to get your actual content. This behavior is required in all properties that retrieve content from an origin.

This behavior in the Default Rule

Origin Server is a mandatory behavior in the Default Rule. An error message is revealed if you delete it, and you need to re-add it. However, you can include an additional instance of the Origin Server behavior in a custom rule outside of the Default Rule. This lets you override what's set in the Default Rule in favor of an alternate origin for various purposes: authorization requests, redirects for downloads, access-denials, failover settings, redirects for special user agents, language settings, or for other needs.

How to configure this behavior

You can set up different types of origin server and there are prerequisites you need to meet before you start applying settings in this behavior. To help with this, we've set up start-to-finish workflows:

• The NetStorage origin server workflow. Here, you use ​Akamai​'s NetStorage service to serve as your origin. It helps automate some of the more complex processes required to set up an origin and integrate it with your Ion property.

• The custom origin server workflow. Follow this workflow if you have your own origin server that holds all of your website or app content that you want to deliver to your end users.

• The third-party origin server workflow. Take a look at this workflow if you're using a third-party cloud provider, such as Amazon Web Services or Google Cloud Storage to serve as your origin server.

Set up HTTP/3

HTTP/3 helps reduce latency and resource consumption when loading web properties. It retains the HTTP/1.1 and HTTP/2 concepts, but it moves away from the traditional transmission control protocol (TCP) transport layer. Instead, it uses the IETF QUIC protocol that handles streams by itself. This supports improved performance and a faster connection setup.

It's included and enabled as the recommended HTTP method in a new Ion property. There are no other settings you need to apply. However, you do need to use transport layer security (TLS) to handle requests from a client to the ​Akamai​​ edge.

You still need HTTP/2

If you still want to accept HTTP/2 requests, the HTTP/2 behavior needs to be enabled in your property, too. HTTP/3 does not replace HTTP/2.

For complete details on HTTP/3, see its topic in the Property Manager user documentation.
