      rabbit.proxy.Proxy

All Implemented Interfaces:

java.lang.Runnable

public class Proxy

extends java.lang.Thread

This is the central dispatcher for RabbIT. Basically it sits in a loop accepting connection and for each connection creating a handler for it. Also handles logging so it goes out nicely formatted (and synchronized).

Method Detail

main

public static void main(java.lang.String[] args)

Start a proxy. Parse flags and read the config, then starts the proxy.

Parameters:

args - the command-line flags given.

startProxy

public static void startProxy()

getTimeZone

Get the time zone the proxy is running in. This is neccessary to give dates in GMT.

getOffset

public static long getOffset()

Get the offset in milis from GMT NOTE! the offset is only calculated at startup. This means that during DST changes this may be invalid for a day or two. Restart RabbIT dayly during that time to get it right _IF_ you feel it is a problem.
