Release Notes:  Dynamic Site Accelerator

New Features:

s-maxage Support. The s-maxage directive is now available to all DSA customers as part of the Caching behavior in Property Manager. S-maxage is a cache-control directive defined by the Internet Engineering Task Force’s (IETF) that makes it easier to configure caching across shared caches in a single setting.  For organizations that use multiple CDNs, this new capability significantly simplifies cache management. 

This is an opt in feature that enables you to define how long content should be cached starting from the time content is requested by configuring Time To Live (TTL) once across Akamai and any other CDNs and intermediary caches. 

The Caching behavior has a new option called Enhanced RFC support, which allows you to honor the s-maxage directive, and other RFC-supported directives, in Cache-Control response headers from the origin.

The latest Property Manager update includes six new rulesets for Ion Premier and five new rulesets for DSA, which appear by default when you configure a new property. These new rulesets encompass 63 configuration changes compared to the previous default settings, in order to help you instantly optimize performance with Akamai-recommended settings. The rulesets are organized in a clean structure, making it easier to understand and maintain your properties’ behaviors. These new default rules help you efficiently onboard new properties and leverage best practices for modern websites, apps, and APIs.  The rulesets include:

• Augment insights. Settings related to monitoring and reporting.
• Accelerate delivery. Settings related to improving the performance of delivering objects to your users.
• Offload origin. Settings related to caching content at the edge and in the browser.
• Strengthen security. Settings that minimize the information your website shares with clients and malicious entities to reduce your exposure to threats.
• Increase availability. Settings that control responding when your origin or third parties are slow or even down to minimize the negative impact on user experience.
• Minimize payload. Settings that reduce the size of the delivered content and decrease the number of bytes sent by your properties.

If you want to configure your properties with the previous default settings, access the classic settings via the Add Rule button while configuring a property. These classic rulesets include:

• Default (classic). Includes the legacy (prior to 2020) default configuration settings.
• Offload (classic). Includes the legacy (prior to 2020) offload configuration settings.
• Performance (classic). Includes the legacy (prior to 2020) offload configuration settings.

The changes will be available for Ion Standard in an upcoming release.
