I manage many sites fronted by Akamai, and it works perfectly to view the cache hit/miss for individual requests. Much easier than running cURL each time.

This extension does the job (extends DevTools Network-tab with akamai-header information) however it's extremely dangerous because once it's activated it will break many requests. For example sites like Favro and Zeplin become unusable. It also destroys some resource requests on my own site. Worst of all is that even if you just use the extension once during a test, then disable it, it tends to magically re-activates itself months later (perhaps when you update Chrome?). We've found that all of a sudden someone in the team sends an alarm about resource requests not working on my site. But it just turns out that they've got this Akamai extension installed and it's magically activated itself without them knowing. Really scary and error-prone extension. It does the job but you basically have to make sure you uninstall it after every time you use it - it's risky leaving it installed and will lead to many herrings as you report suspected errors on various sites, which are just caused by the extension...

It is not working, no additional headers appear when looking at a request from a site being on Akamai.
