Secure forward proxy plugin for the Caddy web server fork from https://github.com/caddyserver/forwardproxy

add an extended configure option called upstreamRule. When upstream is set ,upstreamRule will help to make decision wether forward 'direct' or use ''

Configuration extended (add upstreamRule option)

forwardproxy {
    basicauth user1 0NtCL2JPJBgPPMmlPcJ
    ...
    dial_timeout     30
    upstream         https://user:password@extra-upstream-hop.com
    upstreamRule [whitelist|blacklist] [filepath]

when use 'whitelist', domain in the file will connect directly and the others will forward to upstream
when use 'blacklist', domain in the file will forward to upstream and the others will connect directly
