You can configure a global cache policy to cache static resources on points of presence (POPs). This increases the resource hit ratio, improves access performance, and reduces origin traffic.
Feature | Description |
You can specify whether points of presence (POPs) ignore the question mark ( | |
You can configure browser cache time-to-live (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. | |
The edge cache time-to-live (TTL) is the period of time during which origin resources are cached on Edge Security Acceleration (ESA) points of presence (POPs). When the TTL ends, resources that are cached on POPs are marked as expired. If the requested resource has expired on a POP, the POP retrieves the most recent resource from the origin server and caches it. You can configure a cache TTL for static resources based on file directories or file name extensions. | |
After you enable the development mode, all requests are redirected to the origin server. This allows requests to your website to temporarily bypass the caching components of Edge Security Acceleration (ESA) so that you can verify changes to the cached content. This feature is useful when you want to view changes in real time. | |
After you turn on Sort Query Strings, Edge Security Acceleration (ESA) automatically sorts the query strings in the URLs when processing requests. Then, ESA returns the requested resources from the cache or redirects the requests to the origin server based on the sorted query strings. This way, POPs return the same file for requests that contain the same parameters and values, regardless of the order of query strings in the request URLs. This feature improves the cache hit ratio. |
