------------------------------
Summary: combo_handler does not set the response headers properly
Key: TS-2916
URL: https://issues.apache.org/jira/browse/TS-2916
Project: Traffic Server
Issue Type: Bug
Components: Plugins
Reporter: Feifei Cai
# "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.
