I have a machine setup to run automated tests. I have some software, including Fiddler running as scheduled tasks on start up without user required to log in. I can see tests passing, which means traffic goes through Fiddler, as they would fail otherwise. When I log in to that machine, I can see in Task Manager Fiddler running as background process.

But nowhere I can see the traffic. Fiddler is running as background process and I can't find the folder where it stores temp files. I have also tried setting autosave to a file every 5 minutes. And while it works when I run fiddler in UI, no sessions are saved when it runs as background process.

Hi,
   I am accessing my visual studio project that resides on my laptop from my android phone. Most of it works but i have a java script file called "<script src="~/Scripts/mbsa_js.js"></script>" that shows up in fiddler with a 404. when i access the same file using visual studio, i get a 200. funny thing is that it accepts  "<script src="~/Scripts/mbsa_js.js"></script>" at one point, but in all other calls during this same fiddler process, it shows this  "<script src="~/Scripts/mbsa_js.js"></script>" file it shows 404. 

This gets weider because when i make up a javascript file name that does not exist like "<script src="~/Scripts/mbsab_js.js"></script>" , "mbsab", fiddler shows up as 200. but,as stated, this file name does not exist, how could fiddler show it as 200 instead of 404??

thanks for any advice and help.

I'm trying to write a response inspector, and after trying numerous things, I can't get it to appear on the Inspectors tab.

I've tried this basic test, and it doesn't seem to get loaded into Fiddler:

using System.Windows.Forms;
using Fiddler;
 
[assembly: RequiredVersion("2.3.0.0")]
 
namespace Test
{
    public class TestInspector : Inspector2, IResponseInspector2
    {
        public override void AddToTab(TabPage o)
        {
            o.Text = "TestInspector";
        }
 
        public override int GetOrder()
        {
            return 0;
        }
 
        public void Clear()
        { }
 
        public byte[] body { get; set; }
        public bool bDirty { get; private set; }
        public bool bReadOnly { get; set; }
        public HTTPResponseHeaders headers { get; set; }
    }
}

I've compiled this against Fiddler 4.5.0.0 and 2.5.0.0, and tried loading it into both. Neither seems to work.

I know that my dll is being loaded by Fiddler though. If I add this to the DLL, my Message Box appears while the application is loading.

public class TestExtention : IFiddlerExtension
{
    public void OnLoad()
    {
        MessageBox.Show("Hello Fiddler!");
    }
 
    public void OnBeforeUnload()
    {}
}

I've even tried compiling / loading inspectors I've found on codeplex, but none of them seem to work.

Any help would be greatly appreciated.

hello all ,

  on my mac, I was not able to see fiddler capturing any web traffic. Do i need to set up some thing ?

I checked some other threads, and none are really helpful

I am trying to figure out if the Autoresponder can block a call based on not only the URL but the information in the header so that I can target specific calls from a given url instead of all calls for a given URL. 

 

I am having difficulty figuring out if its possible and if so what syntax for the rule I might use.

 

Thanks

Hello,

 

Is there a possibility to create a click record and script it to relaunch with user request 10x for example?

We need to test our website performances between sections.

thank you,

Hi, 

I'm having trouble getting fiddler to decrypt https traffic with the Requests library in python.  I have an application that is structured like Chrome --> iis --> python --> --> API Server.  Running my application from localhost, it captures the traffic from Chrome --> iis, I need python --> API server.  However, when I attempt the request directly from my IDE it captures python --> API server but the initial POST command to get the necessary token returns this exception:

"(Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),))" .  

I have added the fiddler cert and have confirmed it is in my trusted root certificates in mmc.  This request works as expected when I do NOT have fiddler running.

Any guidance would be much appreciated I have spent a lot of time searching the web for answers.

Thank you in advance,

Daniel
