First of all let me make it more clear. "Fiddler is the one and only, by far the best." (Though I wish it was available on macOS too!)
TBH I'm so new to web debugging. Just having a problem using Fiddler. So let me try to be brief and clear.
I'm visiting a website almost everyday. After logging in, the browser try to send a dynamic long GET request including lots of random characters in its URL.
Nothing to do with the request because the response is the key. Actually, the responds contains a text and I'm going to just eliminate few characters before the response being received by the browser. That's all!
As you can see, it can be done manually but it's so time consuming to do each and every time every hour.
To do that auto, I'm dealing with 2 main problem. First, having no idea how to detect those long random GET requests to Fiddler to make a breakpoint after them and also no idea how to tell Fiddler to try to eliminate the last 10 characters of their response.
I did my best to be clear. Let me know please if it's not. I really need some kind of help.
