Github user sudheerv commented on the pull request: https://github.com/apache/trafficserver/pull/310#issuecomment-150595466 Hmm..the requirement in the jira certainly seems reasonable, but, the current state of this is mainly to ensure ATS is not caching broken responses (connection failure in the middle of download). Allowing to cache the empty docs only when Content-Length=0 indirectly ensures that the response was not broken. So, the patch must somehow ensure that the response is not broken, otherwise, there's a danger of caching invalid responses.
