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? -- Nick Kew --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
