I would like to have users in my company use Fiddler to record web interactions and then export them to Visual Studio webtests. Obviously, this would remove the necessity for many users to have licenses for Visual Studio Enterprise (not inexpensive).

However, my company's website has lots of dependent requests. Visual Studio Enterprise, for the most part, correctly recognizes dependent requests and groups them underneath their parent request after a recording is complete. Fiddler unfortunately does not.

At Sean Lumley's blog at https://blogs.msdn.microsoft.com/slumley/2007/04/17/writing-fiddler-web-test-plugins/ I can see an example for writing a Fiddler webtest-export plugin. I have created webtest plugins before, so this looks like a good option.

Are there any other things I need to know before starting out? Has a dependent request plugin already been written? Unfortunately, I'm not even aware of the algorithm Visual Studio uses for correctly sorting dependent requests.

Hello forum

We intend to use a data recovery software running under Windows which sends "telemetric data" back home (this is declared from the manufacturer). Of course we would like to know everything what this application does...

In the Fiddler docs, different setups are described (e.g. capture traffic from another machine, decrypt traffic from a hostname only)



Question:

What is a good approch to find out, how this application does encrypt it's telemetric data and what kind of "transport-encryption" it does use
(in order to be able to setup a working Fiddler environment)?



Thank you very much for any feedback!

Joe



PS:
I don't want to mention the name of the application in question, in order to prevent the manufacturer to circumvent our efforts :-)

I use Fiddler occasionally. Some time ago it started to offer an update on startup, I agreed, it downloaded new version but ended up with warning attached as a picture.

The message says: The update is not signed by Telerik.

Do I have hacked version of Fiddler or is it the update what is trying to inject some kind of malformed code?

Hello, With recent updates of fiddler it seems as if there are issues running on Windows server core.  (See below for exception from the JIT.)  This hasn't always been the case; I have an installer for an older version that runs just fine.  Is this a known limitation?  any workarounds (besides using an outdated version that I only have access to accidentally)?

Thanks!

Mike

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

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?

 

public void AutoTamperRequestBefore(Session oSession)
{
    if (null == View || View.TextBoxFilter.Enabled) return;
    if (oSession.fullUrl.Contains(View.TextBoxFilter.Text))
    {
        oSession.fullUrl += "&debug=1";
    }
    else
    {
        oSession.Ignore();
    }
}

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!
