How does Akamai cache work?

At Akamai, caching refers to objects retrieved from your origin server and stored at any number of edge servers. Edge servers can quickly deliver the cached objects to your API consumers. Caching decreases the load on your origin server and reduces latency in serving objects to the end client.

What is TTL in Akamai?

Time-to-live (TTL) is the amount of time that an object can be served from the cache. Specifically for Akamai, TTL is the time period an Akamai Edge server may serve an object from the cache without revalidating its freshness with the origin server.

4 Bypassing Akamai by Attacking the Origin By far the most effective way of bypassing the DDoS protection and WAF is to not go through the Akamai network at all. An attacker might also wish to contact the origin server directly to bypass the caching to gather information from the site in a more timely fashion.

How does Internet caching work?

Web caching works by caching the HTTP responses for requests according to certain rules. Subsequent requests for cached content can then be fulfilled from a cache closer to the user instead of sending the request all the way back to the web server.

How do I check my Akamai cache?

If you want to find out the Akamai cache lifetime for a particular object, you can use the command akamai-x-get-cache-key . Akamai has an internal cache key for each webpage or object on the Akamai server. A cache key is a unique identifier that is associated with the value you put into the cache.

What is Akamai cache key?

Cache Keys A cache key is a unique string that lets Akamai edge servers look for your content when requests hit them. It’s made up of a few different pieces (like origin hostname, path, and filename). Selecting the correct cache key will ensure maximum cache footprint and increase cache hits.

What does no caching mean?

How are caching rules used to improve performance?

Caching rules control whether a given object is cached or not. A common way to increase performance is to use caching rules to cache content that doesn’t change very often. For example, images and PDFs files are fairly static, so you could create a caching rule that would cache .jpg and .pdf file extensions automatically.

What are the rules for caching on edge?

Caching rules can be as simple as that, or more complex, such as serving a different landing page to logged-in users. Time to Live (TTL) indicates how long content stays in the edge server’s cache before checking if there is new content on the origin. Once the TTL expires, the edge server checks with the origin to see if new content is available.

What does TTL stand for in Akamai caching?

Specifically for Akamai, TTL is the time period an Akamai Edge server may serve an object from the cache without revalidating its freshness with the origin server. As a guideline, for Akamai caching, if the TTL is short, you’re not achieving maximum offload of your origin servers.
