Similarly, sometimes you just want to make a site function a little different than it was intended, perhaps drop some useful links into a game to speed up your play – or change the style so usability is better.
This is where Fiddler comes in handy, it allows you (amongst other things) to trick any browser into thinking it is fetching a file from a website, when in fact the file could be on another website, or even on your machine!
It works by sniffing what browsers are looking for, and by using your rules it can figure out whether you wish to server a different file, such as a file on a completely different server, Or a file on your desktop! What’s amazing though, is the website still thinks it is from the URI it was originally accessed. Meaning you do not get XSS problems.
