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.
