httptunnel creates a bidirectional virtual data path tunnelled in HTTPrequests.  The requests can be sent via an HTTP proxy if so desired.This can be useful for users behind restrictive firewalls.  If WWWaccess is allowed through an HTTP proxy, it's possible to usehttptunnel and, say, telnet or PPP to connect to a computer outsidethe firewall.If you still don't understand what this is all about, maybe youcan find some useful information in the FAQ file.This program is mostly intended for technically oriented users.They should know what to do.httptunnel is free software.  See COPYING for terms and conditions.If you like it, I would appreciate if you sent a post card to:	Lars Brinkhoff	Kopmansgatan 2	411 13  Goteborg	SwedenInformation and/or latest release should be available from these places:	http://www.nocrew.org/software/httptunnel.html	http://www.gnu.org/software/httptunnel/httptunnel.html	ftp://ftp.nocrew.org/pub/nocrew/unix	ftp://ftp.gnu.org/pub/httptunnelI take no responsibility for what you do with this software.  It hasthe potential to do dangerous things, like disabling the protectionyou system administrator has set up for the local network.  Read theDISCLAIMER file.There are two programs: hts and htc.  hts is the httptunnel serverand htc is the client.  hts should be installed on a computer outsidethe HTTP proxy, and htc should be installed on your local computer.Documentation about how to use the programs should be searched in thisorder:	source code	--help output        FAQ	READMEHaving said that, here's a (probably outdated) example:	At host REMOTE, start hts like this:		hts -F localhost:23 8888	At host LOCAL, start htc like this:		htc -F 2323 -P PROXY:8000 REMOTE:8888	or, if using a buffering HTTP proxy:		htc -F 2323 -P PROXY:8000 -B 48K REMOTE:8888	Now you can do this at host LOCAL:		telnet localhost 2323	and you will hopefully get a login prompt from host REMOTE.See also	http://metalab.unc.edu/LDP/HOWTO/mini/Firewall-Piercing.htmlwhich is a good introduction to firewall piercing.  It also hasdescribes one way to use httptunnel.
