tcp-proxy

in some cases, client may not connect to realServer,in this case, a proxy is required

this is a simple proxy with which when

client -> proxy(ip:port)

it acts like

client -> realServer(ip:port)

the process is like the following

request -> proxy(ip:port) -> realServer(ip:port)
client <- proxy(ip:port) <- response

http proxy

if 192.168.6.88:8080 is a http server

$ tcp-proxy -p 5000 -r 192.168.6.88:8080

after the proxy is startup

$ curl localhost:5000
$ curl 192.168.6.88:8080

generic tcp proxy
