Persistent Connections from Edge to Origin, 300 seconds by default, PS can lower it!
By default, Akamai utilizes Persistent Connections between our EdgeServers and the Origin server. This way we can re-use and pool connections together for faster performance and reducing the overhead on your Origin Server.
By default, we use 300 seconds for these connections and we recommend increasing the timeout setting on your origin to 301 seconds or higher.
Sometimes this is not possible or can lead to issues in your functionality of your web applications, we are able to lower the amount of seconds for the Persistent Connections.
Please keep in mind that this behavior cannot be added by yourself and can only be added and subsequently lowered by Akamai Professional Services.
If you have concerns regarding the settings, please reach out to your account team who can initiate Professional Services to assist with lowering these settings.
