Hello. I installed program on my PC. This program sends POST&GET requests. Fiddler doesn't capture them. I added necessary certificates. and set to decrypt HTTPS traffic from all processes. What shall i do?  

Hi,

Someone please clarify my doubts which are stated below :

1) What is a session in fiddler ?

2) What is  the Difference between Sequence (clock) duration and Aggregate session duration ?

3) What should I understand when Sequence (clock) duration value is greater than Aggregate session duration value ?

4) What should I understand when Sequence (clock) duration value is lesser than Aggregate session duration value ?

Thanks & Regards,

Ritesh

A heads up if you're trying to run Fiddler on a Mac with mono 5.2.  Starting from Mono 5.2, the "mono"command defaults to 64-bit.  Use --arch=32 switch to 32-bit mode to run Fiddler.exe.  

 

mono --arch=32 Fiddler.exe

 

This threw me for a while as I'm not a mono user and Fiddler continually failed on start with the error below.

 

WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all
Stacktrace:

Thanks so much for getting the Mac version of Fiddler started. I know it's buggy and just the first step, but I'm super stoked that this is happening.

Slackware64_14.2

Mono JIT compiler version 4.6.2 (Stable 4.6.2.7/08fd525 Thu Feb  2 14:37:53 CET 2017)

I got a request every 5 seconds from my software to the server in the form

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="default" SOAP-ENV:encodingStyle="default">
    <SOAP-ENV:Body>
<login user="xxxx" password="xxxx" token="jrxrOIX8aziQvGs4" />
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

is there a way i can capture the value of the token and create a new request of a different form with the same token using fiddlercore and c# ?

cheers

So i have the below request

 

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="default" SOAP-ENV:encodingStyle="default">
<SOAP-ENV:Body>
<login user="3602e743d1ba76fb" password="888888" terminal_id="3602e743d1ba76fb" terminal_type="1" mac="08:00:27:db:56:ce" netmode="4" soft_ver="000 pad_1.2.09 eng..20170714.181621" hard_ver="376 KTU84P" epg="epo" token="SKeXAEmnvgBKp74A" />
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

 

How can i replace parts of this in c# such as 3602e743d1ba76fb with another number ?

is this correct ? it doesn't seem to work

 

  Fiddler.FiddlerApplication.BeforeRequest += delegate(Fiddler.Session oS)
            {

                oS.bBufferResponse = true;
                oS.utilDecodeRequest();
                oS.utilReplaceInRequest("3602e743d1ba76fb", "4c1d80a8f35e6a4d");   //userid
                oS.utilReplaceInRequest("08:00:27:db:56:ce", "38:1d:d9:9a:51:a2");   //mac


            };

 

 

Hi!

www.MarketVolume.com provides a Chart that displays data from the stock market. It is available to subscribers that login.

Can I use Fiddler to capture the data that is displayed in the Chart?

In the Chart, I can set the frequency of the update. For example, every 15 minutes the Chart is updated. So, I assume there's a request/response method using login credentials.

 

Hello,
I've got problem with capturing web request sent from my VB.NET ( I think if C# it will be the same ).
If I sent the request without any proxy settings, Fiddler captures it.
If I sent the request with proxy settings even if it's blank settings, Fiddler doesn't captures it.

Here is VB.NET Code which sends a google search request with blank proxy settings.

    Private Sub searchGoogle(ByVal q As String)
        Dim req As HttpWebRequest = WebRequest.Create("https://www.google.com/search?q=" & q)
        req.Proxy = New WebProxy()
        Using res = req.GetResponse()
            Using resStrm = res.GetResponseStream()
                Using rdr As New StreamReader(resStrm)
                    rdr.ReadToEnd()
                End Using
            End Using
        End Using
    End Sub
