I want to limit it to only capture and modify traffic from apps with a specific name or containing a particular string in the window title. Currently, it interferes with Chrome, preventing things like ChatGPT from functioning properly when it's running

The issue at hand involves correctly inputting the required data into the Speakatoo API, but it is not functioning as expected. Further investigation and troubleshooting are needed to identify and resolve the problem, ensuring the API operates as intended.

Hello,

I'm looking to write a fiddler extension following this article: https://docs.telerik.com/fiddler/extend-fiddler/createextension

In this article it suggests linking to fiddler at a hard coded local path.

Is there any way to link to fiddler from a nuget feed, git sub-module or other way or is it best practice to bundle the Fiddler.exe with your application so it can be built without hard-coded paths to locally installed tools? How is this normally done?

Thanks

I would like to use Fiddler Everywhere for remote support and trouble shooting in real time, Is there anyway for the Server to know that the Client is using Fiddler Everywhere as the proxy server if it doesn't modify any data, headers, or flags?

Thanks!

Hi,

I use OnDone to save responsebodies (mostly json data) that match some URL criteria.
I can set different filenames etc. This works fine.
However, SaveResponseBody overwrites the same file if it exists. 

Basically using something like:

if (oSession.url.Contains("some pattern")) {
var directory: String = "d:\\savedir\\";
var path: String = System.IO.Path.Combine(directory + Guid.NewGuid() + ".json" );
oSession.utilDecodeResponse();
oSession.SaveResponseBody(path);
}

Is there also an append mode available on SaveResponseBody so data is added and not overwritten?

Hello Fiddler gang

Found this old post https://stackoverflow.com/questions/43898449/in-fiddler-is-it-possible-to-spoof-the-client-ip-address while trying to find out if there is a way of dynamically directing fiddler to send the requests thru specific IP address (I have a server with multiple IPs).

It suggest using X-EgreesIP so in my fiddler script I added:

oSession["X-EgreesIP"] = "10.10.10.123";

in my InBeforeRequest function but it doesn't seems to have any effect? by running netstat -f it still shows the main IP for establishing the connections to the remote host servers.

The same old post points to another link http://fiddler.wikidot.com/egressip where it mention that it can be configured by command but that means then ALL my requests will go thru that other configured IP, I want to programmatically be able to give a different IP based on the particular request.  Is that at all possible?

Thanks!

Good-day folks,

Hope this messages finds you all in excellent health.  So, I'm in the middle of troubleshooting some issues with a Skype for Business Server and I was instructed to acquire and install Fiddler Everywhere by my internal support team so they can analyze the HTTP traffic between endpoints.  I have been successful in downloading and installing the Fiddler Everywhere application, however, upon launch it is asking me to login or create an account.

Unfortunately, this is a problem for me because the server in question is on a Closed Network, air-gapped, with no Internet access.  Does Telerik offer an alternative to launching the application so it can run in such an environment without requiring a login?  Any help is kindly appreciated, thanks.
