Starman incorrectly prioritizes "Content-Length" over "Transfer-Encoding: chunked" when both headers are present in an HTTP request. Per RFC 7230 3.3.3, Transfer-Encoding must take precedence.
An attacker could exploit this to smuggle malicious HTTP requests via a front-end reverse proxy.
Changed the way server handles HUP and QUIT signals HUP will just restart all the workers gracefully QUIT will gracefully shutdown workers and the master See `man 1 starman` and look for SIGNALS section.
