Source: https://agentreadyhtml.com/vendors/akamai/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # 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. ## At a glance **standards.txt** akamai ```text llms-txt = no statement markdown-negotiation = no statement markdown-twin = no statement initial-html = no statement real-404 = no statement vary-accept = partial ``` 0 supports, 1 partial or announced, 5 no statement. **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.
