David Carlin created TS-2633:
--------------------------------
Summary: 406 negative responses being cached for too long
Key: TS-2633
URL: https://issues.apache.org/jira/browse/TS-2633
Project: Traffic Server
Issue Type: Bug
Components: Cache
Reporter: David Carlin
Settings:
proxy.config.http.negative_caching_enabled = 1
proxy.config.http.negative_caching_lifetime = 500
406 response is being cached, but lifetime isn't being adhered to. They are
cached for much longer, perhaps indefinitely. I have seen Age: increase to
several hours.
With proxy.config.http.negative_caching_enabled = 0 then 406 responses are not
cached.
Bryan pointed out that the docs don't list 406 as one of the cached negative
responses:
http://trafficserver.readthedocs.org/en/latest/reference/configuration/records.config.en.html
The value of proxy.config.http.cache.ignore_accept_mismatch has no bearing on
this issue.
