 - The integrated external API, HTTP (S): SOCKS5 proxy authentication can be integrated with the external HTTP API, which can easily control the user's access through the external system.  
 - Reverse proxy: goproxy supports directly parsing the domain to proxy monitor IP, and then proxy will help you to access the HTTP (S) site that you need to access.
 - Transparent proxy: with the iptables, goproxy can directly forward the 80 and 443 port's traffic to proxy in the gateway, and can realize the unaware intelligent router proxy.  
+- Protocol conversion: The existing HTTP (S) or SOCKS5 proxy can be converted to a proxy which support both HTTP (S) and SOCKS5 by one port, but the converted SOCKS5 proxy does not support the UDP function.  
   
 ### Why need these?  
 - Because for some reason, we cannot access our services elsewhere. We can build a secure tunnel to access our services through multiple connected proxy nodes.

SPS can use existing HTTP (s) or Socks5 proxy converse to support HTTP (s) and Socks5 HTTP (s) proxy at the same time by one port, and proxy supports forward and reverse proxy (SNI), SOCKS5 proxy which is conversed does not support UDP. in addition to the existing HTTP or Socks5 proxy, which supports TLS, TCP, KCP three modes and chain-style connection.
