Demo App says i should use other classes

FiddlerCoreStartupSettingsBuilder<FiddlerCoreStartupSettingsBuilder, FiddlerCoreStartupSettings>.RegisterAsSystemProxy()' is obsolete: 'Please use the Telerik.NetworkConnections.NetworkConnectionsManager to register the FiddlerCore Proxy as the system proxy.'

I referenced the required component, but the class is sealed so i can't create an instance of this class. Documentation covers nothing, it just says the same thing as visual studio do.

I tried to use this in the first place, because fiddler core can't set itself as a system proxy. WinHTTP service is running, still nothing. 

I have an extension that successfully adds a column to the session view. This extension needs to load for saved SAZ files as it is being used for post-mortem debugging by an engineer once the customer has collected the trace. Everything is working great after I worked out how to use FiddlerApplication.OnLoadSAZ to update all of sessions.

Next, I want to add a tab/pane for viewing additional information. I've successfully created the TabPage and added it. It shows up correctly on the right hand side as a new tab. What I want to do is to have the current/selected session information available to the controls on my TabPage. How do I access this information so that it automatically updates when I select a different session? I only care about showing one session. If the user selects multiple sessions, or no sessions, then my tab will just show a message saying "Select a single tab".

I'm trying to run Fiddler on a Win 8.1 machine.

When I run the "fix loopback mess" tool I get an exception reported.

NetIsoEnumAppContainers 0x6f4.

What is the meaning of the exception? 

We are recording a HTTP flow using Fiddler which is invoking an excel and we have macros written (SQL queries) in that excel which will interact with server and extract some data. Those are odata/Queries URLs and these URLs are failing with HTTP 408 (timeout) error message. Could you please look into it and provide some solution.

We have already tried increasing the oSession delay to 1000000 but still observing similar behavior.

Example:
 if (m_SimulateModem)
{
            // Delay sends by 300ms per KB uploaded.
            oSession["request-trickle-delay"] = "1000000";
            // Delay receives by 150ms per KB downloaded.
            oSession["response-trickle-delay"] = "1000000";
}

We are not able to record odata/Queries URL in fiddler, these URLs are failing with HTTP 408 error message.

Please help us to get resolve this issue.

Hi,

I have big issue with fiddler in Windows Server 2012 and IE 11.
When I run fiddler, it offers me WinConfig option to click from top left corner but it throws errors:
Unable to use NetIsoEnumAppContainers to get AppContainer list.
ErrorCode: 0x0
Attempting manual registry crawl; some information will be unavailable.
I am receiving error: Failed to get AppContainer info   as WinConfig action.

 

My Windows Firewall Service in services.msc is started and windows firewalls for  domain, public and private network are off.
I read that for someone starting the Windows Firewall Service resolved the issue but it is already started on my server.

 

I read on internet:
https://blogs.msdn.microsoft.com/fiddler/2011/12/10/revisiting-fiddler-and-win8-immersive-applications/
https://mymemorysucks.wordpress.com/2013/11/12/issues-with-fiddler-on-windows-8-1-and-ie-11/

 

but could not find solution.

What should I do to enable this since I really need Fiddler in order to collect data on the server.

 

Thank you,

Veljko

is it possible transmit not buffered responce when request created by utilCreateResponseAndBypassServer?

code:

on_before_request(Session oSession)
{
    if(oSession.fullUrl=='http../123')
    {
    oSession.utilCreateResponseAndBypassServer();
    oSession.bBufferResponse=false;
    my_curl_downloader(oSession.fullUrl,
    /*on headers line availible*/delegate(byte[] buf, int size, int nmemb, Object extraData)
    {
    var header_str=Encoding.UTF8.GetString(buf);
    //oSession.oResponse.headers.AssignFromString(header_str);

    var header=header_str.split(':');
    oSession.oResponse.headers.Add(header[0],header[1]);
    },
    /*on data availible*/delegate(byte[] buf, int size, int nmemb, Object extraData)
    {
    oSession.state=SessionStates.ReadingResponse;//?????????????
    oSession.responseBodyBytes.append??(buf); //?????????
    })
}
}

Greetings

I was wondering if it is possible to inject location tracking permission into a remote browser and how I can investigate such issue. I saw some ten trackers, and cookies from the suspected site in the Firefox shield feature, and I like to look inside the blocked content. I saw items on hotjar, google analytics, and others. I do have fiddler installed and think I can configure it to see the https traffic. Is there a view that will show me trackers and cookies? What is the best way for me to search for what I am looking for in fiddler please? I am glad to provide more information, pics, etc. 

Hello, I've successfully used FiddlerCore on windows to capture net traffic in Python script.

Now I want to try it on Linux. I followed the guide to install fiddler-linux based on mono, but after installation I don't find FiddlerCore*.dll. How shall I install FiddlerCore on Linux?

Thanks.

Look the screenshot.

All requests have 0 body.

How to fix it?

Thanks.

I'm getting an error on launching Fiddler.  "Port 9000 is in use by process 'zsatunnel:12596'. Would you like Fiddler to use a random port instead?"

If I click yes it doesn't capture anything.   I click no and it suggests I manually configure fiddler. I'm not sure how to proceed. Is there a way to configure fiddler to work in this environment?
