Dynamic Page Caching
Akamai examines the incoming cookies / headers and adds them to the cache
key. This creates multiple versions of the same page based on a known criteria.
The most common use case is to include EdgeScape Data and create
variations of the page based on adding Country to the cache key

Dynamic Page Caching
• Additional Use Cases
• Enabling caching for anonymous user's and by-passing for logged-in users
• Enabling caching for users with an empty cart and by-passing for users with items in
their cart
• A combination of the two solutions above (Cache anonymous users with an empty
cart, but by-pass logged in users or any kind of user with an item in their cart)

Problem Space: Unplanned Application Overload
Spikes that exceed origin capacity can cause:
● Lost transactions
● Abandoned customers/visitors
● Negative brand impact
Deploying additional infrastructure is not ideal
● Cost and complexity to deploy and manage
● Under utilized during normal traffic
Transactions that require your
application to process at origin:
● Shopping cart check-out
● Donation Page
● Service Subscription or
Application
● Form registration
● + more

yes, let normal user access

How Does It Work?
Normal Traffic Flow
● All users are routed to the application
in normal traffic flow
● Application can become overloaded
During Application Overload
● Prioritized users are directed to the
application
● During a traffic surge normal users
are directed to a waiting room while
Akamai checks to see if the
application becomes availableWaiting Room
