 * TITLE:          PhpSploit Class
 * REQUIREMENTS:   PHP 5 (remove "private", "public" if you have PHP 4)
 * VERSION:        1.2

 *
 * 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:
 * [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
 *
