ok, i\'ve been to a lot of challenge sites but i have never been able to get internet challenges. can someone point me in the right direction/tell me what kind of tuts i should be reading?

here a very useful link:

so its the first step. then you can use tools that can change header. (proxomitron) its good if you are in hurry. but i think erik can also upload his tool for that. with that you have to do all that steps alone but you learn more about the topic. and after that write your own tool. its easier as you think.
