I am following along with a pluralsight tutorial on asp.net web.api. http://www.pluralsight.com/courses/one-aspdotnet-from-scratch

The instructor used fiddler to test the web.api outside of the browser using the compose window. I always receive 401 on my get call. So... I hit up the google magic which yielded various possible solutions. I have tried

1. selecting automatically authenticate from the options in fiddler

2. adding this to my web.config

<system.web>
    <authorization>
      <allow users="?" />
    </authorization>
  </system.web>

3. adding the following key to my registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0\BackConnectionHostNames   value of localhost.fiddler

 None of these have worked.

 

What else can i try or what tool can i run to determine what is incorrect?

 

 

 

 

 

 

Dear Sir,

You must have heard of Wechat, do you know how to capture it's traffic when it sends or receives message etc., does it go with HTTP(S)?

I used fiddler to parse many sites

Actually i use Fiddler almost every day, more often than taking a coffee :) 

But today i for the first time got a problem:

when fiddler is running, the website 

https://betfred.mobi/

is not loading, just a ERR_CONNECTION_RESET message appears in chrome

I chaged Fiddler port to 9999, but it did not help

Does anybody has an idea about the reason of such behavior ?

 

Regards

Hello,

 When using Fiddlercore within a C# application is it possible to change the default certificate name when using Makecert.exe?

 Ideally we wouldn't want a popup saying "Did you want to trust ... "DO_NOT_TRUST..." when we reach the point where we want to deploy our application.

 Kind Regards

I've just started to use Fiddler on Windows 10 Enterprise x86 and I notice that whatever website link I open in Firefox or Edge the Response Webview tab in Fiddler is always blank. ​Is there anyway to fix it?

I love fiddler

 

Hi Eric,

I have created a program that "grabs" a link to any video or audio files that are being played in a browser.

(basic summary of what it looks like)

FiddlerApplication.BeforeResponse += delegate(Fiddler.Session oS)
            {
                uriAllowedMediaTypes = oS.oResponse["Content-Type"].ToLower().Contains("video") || oS.oResponse["Content-Type"].ToLower().Contains("audio") ||                 oS.oResponse["Content-Type"].ToLower().Contains("media");
                if (uriAllowedMediaTypes)
                {
                    uriStr = oS.fullUrl.ToString();                    
                    File.AppendAllText(@"C:\Desktop\medialinks.txt", oS.fullUrl + Environment.NewLine);
                }
            };



So for example I can watch a 1mb size video in my browser and I can then later manually download that video, since I know what the url to download that video is (using a download manager of course).
By the time I have finished the manual download I would of used 2mb data (total, 1mb watching and 1mb download). This was my original plan all along.

I then had a lightbulb moment. I wondered if it was possible to watch the video and while the video is playing I was hoping that my fiddlercore program could "copy" the bytes of the video / audio going through the proxy to my local drive.

This way I can have a backup of all the videos I watch on the internet without using extra bandwidth.

So I would watch the video and automatically have a copy saved locally.

In the end instead of using 2mb like my first example. I would of only used 1mb and still have a local copy of the video.

Is there a way to do this in c#? (and if possible also have a variable which holds the number of bytes that have so far been downloaded).

I did some research but only found ways to save the text response and not much else.

Regards
Hendrik 

p.s Would buffering be necessary ?

I tried to run Fiddler on Windows Server 2003, and it just will not load.

Does it run or do we need to load anything else on our Windows 2003 R2 x64 server?

It is loading fine on Windows 2008 R2 X64, but not Windows 2003.

 

I'm using fiddlercore to do some website traffic tests.  Basically, the tests go to a website and verify some http requests were made.  I have a number of different tests that do this across many different websites.  I'm using a test framework that supports parallelism (Nunit 3.0), so I want to be able to run my tests in parallel, but still keep the traffic from each thread separate.  I'm not sure how to do this with fiddlercore, as I can't just give it a process to watch because all of the threads are from the same process.

Whenever I close Fiddler, the SSL protocols I have selected under Tools > Fiddler Options... > HTTPS > Enabled Protocols are forgotten, so the next time I start the app, it defaults to SSL3 only. Is this a bug or a feature, and if the latter, why?
