Hi,

I have a bit of conundrum. We have a webapp wich has built-in NTLM support. However this only works with Fiddler running in capture mode. If Fiddler is not running, the NTLM type 1 message that's supposed to be sent back to the server, by Internet Explorer, for some reason never gets sent.

To clarify, from http://davenport.sourceforge.net/ntlm.html#ntlmHttpAuthentication

=============================================================================================================
3. The client resubmits the request with an "Authorization" header containing a Type 1 message parameter.
=============================================================================================================

(3) never happens, unless fiddler is running in capture mode, then the ntlm handshake works like a charm.

Anyone knows what's going here?

cheers,Ritch

Hi Everyone  ,

I am a BI developer who is moderate experience on C# . I am very a frequent visitor to MSDN forums page , every time i go to web browser to login for seeing recent questions and replies in different languages. Recently i have an idea of developing an WindowsPhone for reviewing these forums in my mobile . 
I thought of implementing  this using RSS feeds of  MSDN forums . I am able to display the content from the forums to my windows App , but i am facing a challenge to provide the ability to user for replying a thread in forums or to a post a new question in forums . As this action requires a login to Microsoft account and this account would validate the authentication of user to perform those actions .

  So i thought Fiddler would help to find out how the request is going to server when i login using my Microsoft account in MSDN forums.  But i am not able figure out how to comprehend this information out of Fiddler . Please find the below snapshot that i got from Fiddler .  As far i understood ,the below highlighted text in Fiddler output is the page which is using to make commuincation to server from my local box .

Please suggest me way to find out how the Microsoft user name and password as being passed to server from my localbox , So that i can use that page in my WindowsPhone  app to make my requirement works.

Thanks in advance  . Any idea would be greatly appreciated.  

The title probably isnt the best way to describe what I need.

I tried using AutoResponder with no luck.
So I need to write a Fiddler Script.

There is a site making a request to a desktop application. (Through a Chrome Plugin.)
Then data is sent to the application which then modifies settings/options (Somewhat) based on that.
The reason AutoResponder wont work as well is because the request has data that is different each time.
So I was thinking about using FiddlerScript to 'match' a certain part of the request that doesnt change and then 'Auto Respond' with a file, instead of the original one.

Can anyone help me on how I would do this in FiddlerScript?

Sorry if its hard to understand, I barely understand all this fiddler stuff with the scripts and such.

But still, if anyone could help I would be SOOO grateful!

Hello, I have a curious problem. I have written a program which uses an algorithm combining a few system variables to create a HWID, and then checks this against some code on my server. If the HWID does not match, the user is kicked out. It's a form of product registration. I am aware that Fiddler is commonly used to bypass such checks, so in curiosity I downloaded Fiddler to see if it could be used to spoof the check. Fortunately, when I loaded Fiddler and started a capture, it did not pick up the traffic. But I for sure am actually not sure why; other requests which the application sends are plainly captured. I have attached both a Wireshark capture and the Fiddler capture. The code to check the HWID is located in /license.php. Wireshark easily picks this up, but it is gone without a trace in Fiddler. So my question is: why is the traffic not being captured? I've checked the source and see no reason as to why it would not be captured.

Hey, Fiddler is a great tool! It's an invaluable part of my workflow, and I really appreciate the work put into it.

My question is , is it possible to use the AutoResponder to respond with a 500 status code, or any other status code than 200 and 404? I have read the AutoResponder docs and can't see anything, but perhaps there's something I'm missing, or some undocumented *action that can do this?

My use case is that I want to test the error handling in my application's REST API by selectively breaking different paths and checking that the UI handles it sensibly.

Hello everyone,
I would like to ask you a question:
I have Fiddler 2 installed and i would like to know if the folloing thing is possible.
I have a program that makes requests over the internet.
I want to know if i can add the responses to Fiddler and when i am not online fiddler automatically to send back the responses i have given.
I heard it is possible but how?
Thanks

I would like to analyze changes in cookie data for the traffic captured during a session.  I don't want to look at each request's "Inspectors > Cookies" panel and do a manual comparison against the cookie values in the previous request.

Is there a tool or technique that automates this somewhat?  Thanks in advance.

Which one does Fiddler go for?  I know there are many in the system and in my case this came up after some suspected corruption due to hardware issues, but I need to get it up and running until the new hard drive goes in.  Any ideas toward this end are appreciated.

if I try to capture the traffic when I login into an website, i can see it only for a second, the it resets, it often redirections me to the homepage and then I get completely new traffic and no infornations about login .how to fix this ?
