Hi,

In the HTTPS tab in Fiddler, I have Fiddler set up to 'ignore server certificate errors' and have the following protocols listed: <client>;ssl2;ssl3;tls1.0;tls1.1;tls1.2

 

When looking at the inspector tab in Fiddler for www.skybet.com, any url related to login (launched when LogIn in the top bar is selected) fails with a 403 i.e. https://www.skybet.com/secure/identity/m/login/mskybet?urlconsumer=https://m.skybet.com&dl=1. 

The only setting in .Net that will return a response for such urls is ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11. Is there some other setting in Fiddler (or in CustomRules.cs) I should change to return a response from such urls?

Thanks!

Hi,

I try to capture my traffic from my App running on an android device (VPN necessary) using Fiddler on Windows 10. The App is using netstandard2.0. So I follow the instruction of this:

   https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/DecryptHTTPS

   https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureForAndroid

   https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureDotNETApp

 

It works all fine without using VPN. But when I activate VPN Fiddler doesn't capture anything of my android device. Any idea?

Hello

Is it possible to save the captured data to one file named "output.txt" and keep overwriting that file for every subsequent write.

So I will always have just one file which will be over-written each time.

Below is my code which generates different files with different filenames.

 

    if (oSession.PathAndQuery.ToLower().Contains("iva/subscriptions"))
        {
            if(oSession.responseCode == 200)
            {
                var directory2 = "C:\\aos";
                var filename2 = oSession.oRequest.headers['SOAPAction'].ToString().Replace('"','') + "_" + Guid.NewGuid();
                var path2: String = System.IO.Path.Combine(directory2, filename2);

                //oSession.SaveRequestBody(path2 + "_request.txt");
                oSession.SaveResponseBody(path2 + "_response.txt");
               
            }
        }

 

Thank you

a

Hello,

 

I'm trying to capture HTTPS traffic made by a command line application I run on the cmd terminal.

I'm using Windows 10, proxy is defined and I capture all communication done from browsers or other applications, but don't see anything when I run this app (which I know for a fact does HTTPS communication).

Am I missing something? Should I define the proxy differently? Please assist.

 

Best,

Segev.

I download Fiddler from fiddler-everywhere-osx. But I found no trust root certificate button in HTTPS tab in Settings.

Then I manually trust the fiddler root cert in KeyChain, but still can't capture any traffic from Safari.

Any one can help on this problem?

Hey,

In fiddler Option-Gateway, we can configure "Manual Proxy Configuration" which fiddler will redirect the traffict to,

I need to create an extension to specify different gateway proxy for different host name, could anyone give me any lead?

For instance, in the extension, If the request host is google.com, I will set Proxy as 192.168.0.1:8000,

if request host is yahoo.com, I will set set Proxy as 192.168.0.1:8001 ...

I can't find any api change the proxy, any help will be appreciated.

Best wishes,

Jessie

Hi 

I want to ask that when will be Fiddler Everywhere with all its webinar demo functionalities (new tabs for session view, filters, comments, auto responder, etc) will be launched

Currently i can't prefer using this version 5, because there are many functionalities of version 4 that are missing in it

I recently installed Fiddler Everywhere for MacOS from the product page https://www.telerik.com/fiddler-everywhere.

However after install I noticed it doesn't have half of the features that all the screenshots and documentation are featuring. Attached is a screenshot of the features I see when inspecting a request to CNN. No Auto Responder features, and no Web Sessions toolbar with filtering. Definitely doesn't match screenshots seen on the product page and documentation.

Is this expected? If so, this essentially makes Fiddler Everywhere for MacOS a glorified Network Inspect panel.

I am also having problems using the "Capture" button as seen in other threads and cannot make it work with restarts, reinstalls, starting in sudo, etc.

Any help appreciated as Fiddler is unusable in this featureless state.
