Steve Jiang updated TS-188:
---------------------------
Attachment: TS188_sjiang_2.diff
It turns out even option 2 is not requiring explicit max-age, only
Cache-Control. So something like "Cache-Control: foo" would have allowed TS to
cache a document with required_headers 2.
I'm attaching a fix to require Expires, CC: max-age, or CC: s-maxage.
> proxy.config.http.cache.required_headers value 1 does not allow caching of
> items with only Cache-Control: max-age

> the records.config variable proxy.config.http.cache.required_headers has
> three options:
> # 0 - No required headers to make document cachable
> # 1 - at least "Last-Modified:" header required
> # 2 - explicit lifetime required, "Expires:" or "Cache-Control:"
> The options are ordered in least restrictive to most restrictive. However,
> choosing option 1 does not allow YTS to cache objects with CC: max-age,
> whereas option 2 allows it.
