hi all,

hoping to understand why i cant seem to install Fiddlercap on the directory i want, it seems that using /D= its possible but i cant seem to get it working.

i tried without the /S option with /D=E:\apps\Fiddlercap and i always get the installer showing my desktop path.

Appreciate any help, thanks in advance!

Hi,

I want to automate the uninstall of Fiddler by using the "uninst.exe /S".

When we uninstall Fiddler double-clicking uninst.exe in UI mode we have the question asking if we would like to keep Fiddler's configuration.

How can I keep such configuration by the command line, without UI, with the /S switch?

Thank you,

Kind Regards,

Gustavo

Hi

Is it possible to create FiddlerCoreStartupSettings to intercept requests for a specific host only? Or alternatively a specific program.exe?

I recognise there is a bypassHost options, but its not clear how to add multiple hostnames to that string?

Thanks

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

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
