  +--proproxy.ProProxy

public class ProProxy

extends java.lang.Object

ProProxy
Generic cascading proxy server. Can be used for any single socket network application - HTTP, telnet, blah blah..
One of the few proxy servers that support both UDP and TCP sockets.

Usage: java proproxy.ProProxy

Configuration file format:
# Debug mode (true or false). All messages will be logged in debug mode.
# DEBUG =
# Protocol for which this proxy is to be used
# Any one of udp, tcp, http or chttp
PROTOCOL =
# The port number on which ProProxy will listen for incoming requests
LISTEN_PORT =
# If proproxy is being used in cascade mode (udp or tcp protocols)
# the host address to which the requests are to be forwarded
CASCADE_HOST =
# If proproxy is being used in cascade mode (udp or tcp protocols)
# the port number on the target machine to which the requests are to be forwarded
CASCADE_PORT =

# List of IP addresses who are not allowed to connect to proxy
REJECT_IP_LIST =
# List of IP addresses who are to be allowed to connect to proxy
ALLOW_IP_LIST =


If cascade port is not specified it is same as listen port.
Cascade host and port are not used if protocol is http or chttp.
Protocol chttp is HTTP mode with compression.
If REJECT_IP_LIST list is specified, ALLOW_IP_LIST will be ignored.
If neither is specified, all connections will be allowed.
Lists can contain valid IP addresses separated by space.
