I'm working on a web application that makes calls to a web service on another server. When I'm debugging my application in Visual Studio, I'd like to be able to see the sessions to the remote service initiated by the application as it runs in IIS Express.

Is this possible?

In this case, Let's take Google Search as example:

if (oSession.uriContains("&q="))  {
var str = oSession.fullUrl;
var sAppend = "test1+test2+test3";
if (!oSession.uriContains(sAppend))
{
oSession.fullUrl = str.replace( "&q=","&q="+sAppend);
}
}

For those who are confused, It says, If &q= is present in the URI, replace/append &q= with &q=test1+test2+test3

Problem: It appends test1+test2+test3 instantly, when it sees &q= in the URL.

Basically, how do I make it wait until I click the submit/search button

Thank you.

Hello!

What is the reason behind prohibition of the running secondary (tertiary, and so on) instance of Fiddler?
I need to monitor 3 copies of application -- PC app, WP8 app, and OSX app (FiddlerMono is really sucks and hangs, unfortunately).
It is quite handy to use several copies of Fiddler to avoid the hell of sessions mixing.
The solution I'm using now -- "run as another user". But it's not quite handy if I run more than 2 copies at once.

Could you please add an option like "-secondary:port" that will skip a running application check and start Fiddler with different port (which could be indicated at window caption) ?

Will be glad to any reply!

Hi,

I am new to Fiddler and web development in general.  I am trying to get Fiddler to work with Firefox but I can not find this Fiddlerhook extension that is talked about

Good day Fiddler Team.

We have a unique environment and make use of your tool to determine where bottlenecks occur on the fly.
We use PSTools to connect to the machines, install and start the program silently.

Is there a way to start fiddler specifying a ".saz" file location to save when the stop command have been given?

Can you perhaps build this functionality into fiddler or does it exist already?

Kind regards

I'm using fiddler to debug the http requests of a program that I'm currently writing. So I'm constantly closing and recompiling the program and get a different exe everytime. 
I tried the "Select process" feature, but it seems to get sticked to a specific PID, so I would have to select my program every time I run it again. 
The problem with that: My program does an http request right after it's started, so this isn't gonna work. 

So for now the best thing I can do is to set Fiddler to ignore browsers. But for some reason, some applications just send their traffic through Fiddler even though I haven't configured then to do so. 
For example Skype and TeamViewer do a lot of http requests in the background and while you download a game on Steam it gets really insane...

So how can blacklist Skype, TeamViewer and Steam? Or how can I simply disallow programs from using Fiddler without me allowing it?

Best regards,
Fabian W.

Hi ! I manage to capture the selected session in auto responder and manipulate the same URL offline.
The session I have is involved client and server , this is a game. I am here to ask some question.

A.) I have extracted the selection session in auto responder in Raw file. Mean (Dump all the file in my dekstop)
      I have try to launch the file in my dekstop but it does not allow me to play back the session, maybe there is a client and server involved.

B.) Can the Raw file created by Auto responder - move all the files to IIS2. I am running Windows 7 professional.

I'm tired of manually adding "dog" every time I search the web.

For example:

I do not want the "dog" appearing in my search results

https://www.google.com/search?q=cat+-dog

https://www.google.com/search?q=baseball+-dog

I'm new to Fiddler,So please give me a good hint.

Thanks

After installing the Fiddler Cert Maker plugin, I'm greeted by a warning when opening Fiddler that my software is out of date for the Cert Maker. The CM wants version 4.4.9.4 but the most recent one on the Fiddler site is 4.4.9.3.

I have an ASP.NET WebForms app (sender) which sends a WebClient post request to another ASP.NET app (receiver) on the same dev machine. The WebClient post is initiated by clicking a button in the sender app. It's a test app and the form has only the button. I can see the post from the button in Fiddler but I don't see the post request from the WebClient method. Why?

I know the WebClient post runs successfully because the breakpoint is hit in the receiver app and the Forms collection has the value of the input field from the WebClient request from the sender app. (Using Windows 8.1)

This is the call:

using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
var data = "FirstName=John";
var result = client.UploadString("http://localhost/testform/default.aspx", "POST", data);
Console.WriteLine(result);
}
