--------------------------------------

My fix to TS-3331 might have helped this one too...

> 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.
