This behavior activates persistent connections between edge servers and clients, which allow for better performance and more efficient use of resources. Compare with the persistent​Connection behavior, which configures persistent connections for the entire journey from origin to edge to client. Contact Akamai Professional Services for help configuring either.

This behavior is only supported with the HTTP/1.​1 networking protocol that's automatically enabled in all properties. If you include this behavior in the same rule with http2 or http3, edge servers honor requests using either of these protocols, but the settings specified in the persistent​Client​Connection behavior won't apply. Both http2 and http3 apply persistent connections automatically.

Warning. Disabling or removing this behavior may negatively affect performance.


Enables the persistent connections behavior.

timeoutstring (duration)

Specifies the timeout period after which edge server closes the persistent connection with the client, 500 seconds by default.
