Hi

I need send a specific request and use one parameter of its response to send another request.

Is it possible to do it? for like 100 times?

How should I start? Any example or tutorial?

Good afternoon! 

We're looking to use Fiddler for troubleshooting on-demand and want to be able to do some automated install/uninstall pushes.  Are there any silent or unattended options that can be used with this installer?  Or perhaps an MSI package rather than the provided EXE?  And once it's installed, is there a way to automatically configure some general parameters, like disabling the autocheck for updates and preventing the autoload of the website on first run as it's inaccessible from our environment anyhow?  Thank you for your assistance!!  :)

Web server host on remote box, I have fiddler set up with a Host filter to "Show only the following hosts" http://192.168.48.64:3005/;

Fiddler reports "Capturing" but no traffic is coming through, despite using and refreshing the webpage repeatedly. I've even used Postman to issue a simple login GET. While filter is active, all traffic is removed from feed. Only using "Help > Troubleshoot" reveals all traffic with strike through, but unfiltered traffic is better at that point because it lacks the strike through.

Switching Host filters to -No Host filter- and instead turning on Client Process "Show only traffic from" application, and using that application to generate traffic did work.

Using Google chrome and Postman to create traffic.

I'm having trouble with Fiddler on pages using server-sent events. The eventsource just stays in a pending status if Fiddler captures the request. I don't need to inspect the events in Fiddler, but I would like to be able to inspect the other requests in Fiddler without breaking the page.
 
While Fiddler is capturing sessions:
  1. Run a server side event server such as https://github.com/hemanth/sse-now
  2. Open a page that connects to the server (below)

Result: Events are not received

Following the same steps while Fiddler is not capturing sessions, everything works as expected. Enabling streaming does not solve the issue.

Is this a bug in Fiddler or is there some way I configure Fiddler to handle this?

 

Example testSSE.html

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>SSE demo</title>
</head>
<body>
 
</body>
<script>
var source = new EventSource('http://localhost:8000');
source.onmessage = function(e) {
  document.body.innerHTML += e.data + '<br>';
};
</script>
</html>

Hello!

This might be the most random post ever, but I really need help. I’m new to Fiddler. Just installed and I don’t know a lot of things. I’m experimenting with it, but still nothing..

So I need some help...This is quite embarrassing, but anyway, I need help on this website game called MovieStarPlanet. Yeah, it’s a dumb game, for kids and teens and all that, but I’m only playing it to collect items that are so called “ultra rare”. That’s cringy, and I’m too old for it, but anyway..

If anyone is really good at this program can you please tell me? I will give more  details on what I need, but first i’ll give some here too.

Basically, there is a “beauty clinic” ( oh God this sounds so cringy) where you can change your skin, lips, makeup, etc. People have been pretty obsessed with this “rare skin” that isn’t in the store. Everyone wants it because it looks “aesthetically pleasing”. I want it for some various reasons, but I don’t know how. There used to be another glitch using another program (won’t mention no names), but that sadly got patched. I knew how to do that glitch though. 

And now here we are, 2018! The possible way now is with Fiddler. I experimented a bit and found something, but I’m sure missing something and that’s why it won’t work. 

Please tell me if you know this program well, i’ll try to explain it very well! Thanks!

Hi

I have a very strange problem. It is not fiddler related, but fiddler actually fixes it! But I hope someone here can shed some light on what is going on.

I am trying to have a client (Internet Explorer) connect to a webserver (IIS) with Kerberos authentication. I access the website with the DNS name for the server (myapp.domain.net) as URL. When fiddler is NOT running on the client machine this happens:

1) Client sends GET request to webserver
2) Webserver responds with 401 and WWW-authenticate set to Negotiate
3) Client sends AS request to domain controller
4) Domain controller sends AS response ticket
5) Client sends TGS request to domain controller. Inside the request is the FQDN(iisservermachinename.domain.net) of the webserver.
6) Domain controller sends S_PRINCIPAL_UNKNOWN to client
7) Client sends GET request to webserver with an NTLM NEGOTIATE MESSAGE inside
8) Webserver sends 401 with an NTLM CHALLENGE MESSAGE
9) Client sends GET request to webserver with NTLM AUTHENTICATE MESSAGE inside
10) Webserver replies with HTML

This gives NTLM authentication and not the Kerberos authentication I want. 

The strange thing is step 5). When fiddler IS running, it puts myapp.domain.net in the TGS ticket instead of iisservermachinename.domain.net. And then everything works because then it hits my AD SPN's.

Can anyone tell something about what is going on here?
