Re: GZIP DEFLATE and HTTPD

Per Akamai Guy, Vary shows akamai that content can vary so akamai is not caching, and this leading akamai to make requests to our webversion ...
We mostly just use JS and CSS to be served from akamai ..

If you omit a Vary header, you're telling the cache you can't supply
other variants.  That leaves the cache the choice of returning the
wrong contents to some clients, or returning an error.  Or perhaps
ignoring the HTTP spec and asking the backend every time,
which would undermine all the benefits of HTTP cacheing.

Sounds like akamai is broken.  Or rather, not configured to cache
negotiated contents.  Does it also refuse to cache multilingual pages?
