Hello Fiddler team,
Can you please tell me on how to achieve this. I am using classic fiddler.
I will send requests continuously. If response of the request is 'true', there is no need to worry. Till here no worries. But I want to break on new requests when response is false. How can this break be achieved?

.

I want to use AutoResponder to mock a response from my server. The response in question is JSON object and I need to tweak its properties slightly. The thing is I cannot seem to do that via the Edit Response menu in Fiddler. Here's a screenshot: http://screencast.com/t/1f7iNWTF1NX9

There's something called "Send to TextWizard" but I don't know what that's about.

Thanks

How to cancel the highlighted?
I'm afraid the software of progress telerik fiddler web debugger does not have this capability.

I reviewed the content on this link. I added the nuget library. Why can't I use these codes? When using it with C #, I get an error as I mentioned in the appendix. "'oSession' does not exist in the current context" What is the cause of this error? I cannot use any code related to Fiddler. What causes the oSession error? I want to work on FiddlerCore, but I couldn't find a solution for this error.

I tried to redirect all traffic thru Fiddler by using redsocks and iptables. Plaintext HTTP seems to work fine, however HTTPS doesn't seem to work properly.

Initially I didn't want to use redsocks at all - however it seemed that Fiddler cannot work in the way similar to sniproxy: using iptables -j DNAT alone doesn't work at all.

Then, although redsocks supports http CONNECT proxy mode, Fiddler no longer shows domain names in intercepted CONNECT entries - IP addresses are shown instead. Fiddler also throws out certificate errors, even if I check the "ignore certificate errors" checkbox, the intercepted application (which already trusts FiddlerRoot certificate) still refuses to connect. I think this should be related to SNI.

I think if Fiddler could work in the way similar to sniproxy, this problem would no longer exist, probably.

Hello,

Is it possible to capture localhost (client and server) websockets communication?In my case, in the client side I am using javascript code to connect to the websocket server, that it is started using java language.

In fiddler I do not see anything...

Hello,

Is there any way to decompress post data in Fiddler, sent from application? Post request to server contain headers like this:
Content-type: application/x-compressed-json
Content-length: 3xx

Sent JSON data is unreadable. Any ideas are welcome! 

Hi everyone. I'm using Fiddler Everywhere on mac to intercept calls from the smartphone app to the vaccum robot, so i can use those commands to integrate the robot into my home automation system (Home Assistant).
so I set up Fiddler Everywhere, set up the proxy in the ios wifi and installed the certificates, and correctly intercepted the commands sent.
however, there are some "parameters" that i can't intercept, let me explain with one of the cases as an example: the robot obviously drains the battery when it's working. when it finishes cleaning, it goes back to the charging base. keeping the mobile phone active during the robot charging process, I see that for every percentage point of charge acquired, a post call is sent, of which I see url, headers and payload, but there's absolutely no trace of that percentage value (or any other info related to the battery). however, obviously on the smartphone I see that variation, so somehow the information has to go through.
so the question is: what can be the case that I can't catch THAT particular detail? what tests can i perform?
I hope I've explained it well enough, if necessary I can provide screenshots (app screen and details of the intercepted traffic).

Thanks
