Very interesting, thanks! Looking forward to the next tutorials :)
If the following is not okay to ask, please edit:

kind of a old bump (by lugz :P)... but interesting read... I did not know you could use two dots to go back a directory over the web.... This is pretty much the only type of exploiting I knew anything about (kind of the reason I found this site).
Tnx for the tutorials slysnake.... Wonder if you ever posted part 3 :P
