Bryan Call commented on TS-1468:
--------------------------------

Talked to Mark Nottingham about checking Vary and Accept on all response codes (2xx, 3xx, 4xx, 5xx) and he didn't see any issues with it.

> ATS doesn't look at the Accept* and vary headers when trying to find an alternate in cache for non-200 responses from the origin.
> Webdav is effected because of 207 response from the origin and ATS doesn't check the Accept* and vary headers.  If there is gzipped data in cache and a non-gzipped request comes in, the gzipped version will be handed back to the client.
> There is an option for YTS to always look at the Accept* and vary headers, but it is not in ATS.
