ruby-httpclient 2.7.1-1ubuntu1 (amd64 binary) in ubuntu artful

 httpclient gives something like the functionality of
 libwww-perl (LWP) in Ruby.
 .
 Features:
    * methods like GET/HEAD/POST/* via HTTP/1.1.
    * HTTPS(SSL), Cookies, proxy, authentication(Digest, NTLM, Basic), etc.
    * asynchronous HTTP request, streaming HTTP request.
    * by contrast with net/http in standard distribution;
          o Cookies support
          o MT-safe
          o streaming POST (POST with File/IO)
          o Digest auth
          o Negotiate/NTLM auth for WWW-Authenticate (requires net/htlm module)
          o NTLM auth for WWW-Authenticate/Proxy-Authenticate (requires
            win32/sspi module)
          o extensible with filter interface
          o you don't have to care HTTP/1.1 persistent connection (httpclient
            cares instead of you).
