Thanks for your answer,
I have a another question, I need to use fiddler as a windows service while saving http traffic. I tried 2 options that used FireDaemon and AlwaysUp.
But in both cases i can't log my traffic. Do you have any suggestions ?
For example if i install fiddler to a client computer i need fiddler to start automatically at each startup and log traffic until the user turns off his computer.
