version 1.0
	**	Provide a robust method of reading HTTP requests. Should be
		fully compliant with HTTP/1.1 persistent connections. The log
		file includes the request number send over the same connection.
	**  Provide an access control list for restricting who is allowed
		access to the transparent proxy. This is much faster that using
		tcp_wrappers for this function.
	**	Allow tcp_wrappers as an alternative to provide host access control.
	**	Fixed up the remapping of a URL to a fixed location by allowing
		accesses to documents referred to by the fixed location. This should
		allow images and SSI cgi-bins to work.
	**	Transparent mode now directly contacts the original source rather
		than the proxy. This allows transproxy to function as a HTTP proxy
		on a firewall without a cache.
	**	Transproxy will now try to connect to the original source if it fails
		to connect to the cache proxy.
	**	Only allow server mode specific command-line switches when server
		mode has been enabled.
	**	Provided tproxyrun and tproxywatch as examples or usable scripts.

version 0.6
	**	I have decided to use a BSD style COPYRIGHT rather than the
		FSF COPYLEFT. I feel that it is much less restrictive.
	**	Installed binary is now called tproxy instead of in.tproxyd.
	**	Log access to a file is now supported with the -l switch.
		See the make file for automatically opening the log file.
	**	(Bill 'Gates' Evans <evans@nasp.cnet.navy.mil>) Implemented
		a no-daemonise mode. With the -d switch tproxy doesn't go
		into the background. Usefull when running from inittab.

version 0.5
	**	(Vesselin Atanasov <vesselin@bgnet.bg>) Implemented changes
		to lookup the proxy host for each request, hence allowing DNS
		round-robin load sharing.
	**	(Vesselin Atanasov <vesselin@bgnet.bg>) Included a patch
		(after coding standard changes) to fix operation with
		HTTP/1.1 persistent connections by forcing them to be disabled.
	**	Added some options to either disable syslog(3) logging,
		use it only for errors, or use it for everything. Check
		the Makefile.
	**	Some minor buglet fixes to operation under error conditions.
	**	(Krzysztof Adamski <kadamski@netsurf.net>) Added remapping of
		url to a fixed location.

version 0.4
	**	Fix up README file bug about the /etc/services file entry.
	**	Applied BSD patches so that it works with the IP filter.
	**	Some errno.h and SIGCHLD changes to compile with other
		systems and the new linux glibc.

version 0.3
	**	Use the SO_KEEPALIVE socket option to allow the TCP/IP
		layer to detect when a connection has gone away.

	**	Set an alarm for 5 minutes to detect an idle connection.

version 0.2
	**	Parse the request headers looking for a "Host:" header to try
		and find the real host name the request was being sent to.
		When this works out it means no DNS lookups at all. More work
		needs to be done on reliably searching the headers.

	**	Use setuid/setgid instead of setreuid/setregid so that the
		saved uid and gid also get set.

	**	I found that if a set the SIGCLD singal to SIG_IGN then I
		don't have to worry about children or zombies!

Version 0.1
	**	Initial version.
