Hello, I have a curious problem. I have written a program which uses an algorithm combining a few system variables to create a HWID, and then checks this against some code on my server. If the HWID does not match, the user is kicked out. It's a form of product registration. I am aware that Fiddler is commonly used to bypass such checks, so in curiosity I downloaded Fiddler to see if it could be used to spoof the check. Fortunately, when I loaded Fiddler and started a capture, it did not pick up the traffic. But I for sure am actually not sure why; other requests which the application sends are plainly captured. I have attached both a Wireshark capture and the Fiddler capture. The code to check the HWID is located in /license.php. Wireshark easily picks this up, but it is gone without a trace in Fiddler. So my question is: why is the traffic not being captured? I've checked the source and see no reason as to why it would not be captured.
