Hey,

I creating a UI that has an input box to set a filter. It is then disabled and traffic should be filtered based on it. Along with filtering, any traffic that matches the filter text has a parameter added.

 

I think this should work in principle, but practice it is usually not working. It sometimes works and sometimes doesn't. Am I doing something wrong?

I am struggling with a Windows 10 Pro version 1709 machine. When I am connecting to my ADFS form IE11 and I start capturing with fiddler, it will error.

I reset the certificate, I disabled proxy in the options and I also tried disabling WIA. When I access from Chrome, it works fine but with IE11, it does not matter what I do, it wont work. 

As a test, I created another virtual machine with same characteristics, and it works just fine. The only thing I did different is that on the machine that is not working, I did not run IE setup, on the other one that works, I did it.

 

 

I've noticed very recently that SNMP Service on Windows 10 seems to run constantly on my Windows 10 PC System. The Task Manager shows it consuming 15-20% of CPU resources on a regular basis. I want to kill the service but something on my system is probably dependent on it.

Is it Fiddler or should I look elsewhere?

Thanks for reading!

Hello,

how to configuration fiddler for capture all traffic between my APP and SQL server?? such as all queries, transactions, connections, etc. 

 

Thanks

 

Hello,

this might not be directly related to Fiddler functionality, but I've been trying to cleanly reinstall Fiddler with no luck. What I did:

- I removed the extracted `fiddler-mac` directory from my `/Applications`.
- I removed `Fiddler2` directory from my home dir.
- I uninstalled Mono.
- I installed Mono and extracted `fiddler-mac` ZIP archive again to `/Applications`.

When I run `mono Fiddler.exe`, Fiddler keeps maintaining its previous UI states (window size, column-widths, toggled options, etc.) and it doesn't even reset the "About" info, i.e. "You've run Progress Telerik Fiddler: 32 times." instead of resetting the count to 0.

Are there any Fiddler-related preference/config files stored somewhere which I may have missed to remove? (I have looked into `~/Library/Preferences` and `"~/Library/Application\ Support"` to no avail)

Hi ,
How can I decode the  WWW-Authenticate header in c#.
I have the following header :
Authorization: Negotiate TlRMTVNTUAADAAAAGAAYAIAAAAAYABgAmAAAAAYABgBYAAAADAAMAF4AAAAWABYAagAAABAAEACwAAAAFYKI4gYC8CMAAAAPffbxvOGkL8ns+08wCF8mpUcARQBSAHMAawBhAHIAbgBpAFMASwBBAFIATgBJAC0ATQBPAEIATABmpA4p85r6qgAAAAAAAAAAAAAAAAAAAADhTsbpNSiV0RYcgZydNiGaRJqQVfHQAM80vSRnAZubLRwjwE2TnLrY

I (guess), that the information presented in the "Auth" tab is the decoding of this header.
A'm I correct ?
How can I do it in C# ?
thx
Sagi

I upgraded to v4.6.2.0 and the HTTPS decryption option is causing sites to fail to load in my browser. I have tried disabling and re-enabling decryption without any success. This was working before the upgrade. Does anyone have any suggestions?

Hello, I have downloaded Fiddler for Mac from this link: https://www.telerik.com/download/fiddler and have followed the installation instructions regarding mono and placing fiddler.exe in a writable directory. When running "mono fiddler.exe" from my terminal, Fiddler starts up. However, it is not automatically capturing web traffic like I am used to it doing on Windows.

Is there some other step that I need to perform on Mac for it to start capturing web traffic?
