> # "Cache-Control: max-age=xxx"
> combo_handler plugin should parse each url's max-age value in "Cache-Control" header, and use the minimal value in the response header. The hard-code "10 years" max-age prevents cache from refresh, even though we have parsed the value in "Expires" headers.
> See [rfc2616-sec14.9.3|http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.3]:
> "If a response includes both an Expires header and a max-age directive, the max-age directive overrides the Expires header, even if the Expires header is more restrictive."
> # Duplicated headers
> We add support for whitelist of headers in a recent [commit|https://github.com/apache/trafficserver/commit/f61b1b416f4bb99854c6b6c77b12f742b5af9ca8]
> When we have added headers specified in whitelist, we need to check for duplicated headers in the following response write actions.
> # Multiple values
> Some headers has multiple values, e.g. "Cache-Control: max-age=3600, public". It has 2 values: "max-age=3600" and "public".
> We need to parse all the values for each header specified in whitelist.
