Akamai: vendor profile

In short

A Remove Vary Header behavior lets Akamai cache responses that would otherwise vary on Accept, and Akamai prefers removing the header at the origin. EdgeWorkers needs an entitlement on the customer's contract. Akamai's techdocs point agents to an llms.txt index and .md copies. akamai.com answered the crawl client with 403 on 2026-11-05.

Akamai Host, CDN or edge product

CDN and edge platform. Akamai edge servers do not cache responses that carry a Vary header other than Accept-Encoding, which matters for any site that negotiates markdown, and EdgeWorkers can run JavaScript on requests and responses.

What it does for this layer

Akamai's Property Manager docs say edge servers do not cache responses that include a Vary header, even when the content is cacheable by definition. [primary source] source, read 5 November 2026.
The one exception Akamai documents is Vary: Accept-Encoding with a Content-Encoding of br or gzip, which edge servers cache under the property rules. [primary source] source, read 5 November 2026.
Akamai's Remove Vary Header behavior, when set to ON, strips Vary headers other than Vary: Accept-Encoding so responses can be cached; removing the header at the origin is the method Akamai prefers. [primary source] source, read 5 November 2026.
Akamai EdgeWorkers deploys JavaScript functions to Akamai edge servers, invoked on specific events in the request and response cycle. [primary source] source, read 5 November 2026.
Akamai states an EdgeWorkers cold start time for first execution of less than five milliseconds. [vendor claim] source, read 5 November 2026.
EdgeWorkers needs an entitlement on the customer's Akamai contract and a supported delivery product as its base layer. [primary source] source, read 5 November 2026.
Akamai's techdocs site tells agents that each docs project has an llms.txt index and that appending .md to a documentation URL returns its markdown version. [primary source] source, read 5 November 2026.

What it does not do

Akamai does not cache a response that varies on Accept, so a markdown-negotiating origin behind Akamai either loses edge caching or must drop Vary and risk mixed cache entries.
