Hello, I'd like to confirm concept of "Remove Vary Header".

I could understand that akamai platform not cache the contents with the vary headers other than Accept-Encoding, since the content might be changed. 

 

So this header(and value) is used for notification of downstream cacheability.

If above understanding is right, the way of the behavior seem to be bringing wrongly caches.

 

Is there known proxy or web product (or clumsy app?) that add unexpected vary headers?
