Description

HTTP/1.1 500 Internal Server Error
Content-Type: text/plain
Cache-Control: no-cache

Server: ATS/3.3.5-dev

While this is a grey area since we are already breaking the spec by negative caching, I think we should still not cache this when explicitly told not to by the origin and zwoop agrees!
