The browser cache time-to-live (TTL) is the period of time during which web page resources, such as HTML, CSS, JavaScript files, and images, are stored in the cache of browsers. By default, the TTL follows the Cache-Control header that is configured on the origin server. You can configure the browser cache TTL without modifying the configuration of the origin server. During the TTL, the browser loads the files from the cache for subsequent requests. This speeds up page loading.
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 pane, choose .
In the Browser Cache TTL section, click Configure and select a cache policy.
Honor Origin TTL: The browser uses the cache policy that is contained in the response from the origin server. If the response from the origin server does not contain a cache policy, the point of presence (POP) does not add a cache policy to the response.
Do Not Cache: All resources that are received by the browser from POPs are not cached, regardless of whether the responses from the origin server contain a cache policy.
Use Custom TTL: The TTL that is configured on POPs is used, regardless of whether the responses from the origin server contain a cache policy.
Click OK.
