Hi,
I see the response can be cached. Will try out increasing logging level of
cache.log

General
- The Content-Type header's syntax isn't valid.
- The Keep-Alive header is deprecated.
- The server's clock is correct.
Caching
- This response allows all caches to store it.
- This response allows a cache to assign its own freshness lifetime.
Thanks,
Hari
