If you do not want Edge Security Acceleration (ESA) to cache some resources that match the default cache rules, configure a cache rule to filter requests to the resources, and then set Cache Eligibility to Bypass Cache for these requests.
When to use it
To prevent caching dynamic resources at ESA points of presence (POPs), set a cache rule to bypass the cache for those resources. This ensures that POPs retrieve the latest version of each requested resource from the origin server, improving resource access performance.
Set up bypass cache
In the ESA console, choose Websites. In the Website column, click the target website.
In the left navigation pane, choose .
Click Create Rule and enter a Rule Name.
In the If requests match... section, set the request features to match. For more information about how to configure rules, see Rule expression components.
In the Cache Eligibility section, select a caching policy.
Bypass Cache: All requests bypass the cache component on POPs. This allows clients to retrieve the most recent resources from the origin server. When you choose this option, you can only configure Browser Cache TTL.
Eligible for Cache: All requests eligible for caching pass through the cache component on POPs, and POPs return the requested resources without retrieving resources from the origin server. This speeds up the response time of your website.
Click OK.
