If you do not want Edge Security Acceleration (ESA) to cache some resources that match the default cache rules, you can configure a cache rule to filter requests to the resources, and then set Cache Eligibility to Bypass Cache for these requests.
Procedure
Log on to the ESA console.
In the left-side navigation pane, click Websites.
On the Websites page, find the website that you want to manage, and click the website name or View Details in the Actions column.
In the left-side navigation tree, choose .
Click Create Rule and specify the Rule Name parameter.
In the If requests match... section, specify the conditions for matching incoming requests. For more information about how to configure a rule, see Overview.
In the Cache Eligibility section, select a caching policy.
Bypass Cache: All requests bypass the cache component on points of presence (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.
