# This is a SOCKS monkey patch for Faraday, with example use/unit test.
# Notes:
#    * It is altered to work with SOCKS5 authentication.
#    * net_http_class must return a Faraday::Adapter::NetHttp instance.
#    * Verified as of 2020-02-24 with:
#        - SOCKS5 ss5 server
#        - gem faraday, '1.0'
#        - gem socksify,'1.7.1', git: 'git://github.com/pirateradio/socksify-ruby.git'
#        - ruby 2.6
