Great, I installed the fiddler update. Now I can no longer decrypt https client traffic while debugging.... 

"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel"

 

 I had the fiddler cert trusted before and didn't get a prompt to trust it when enabling https decryption.

 

So I uninstalled Fiddler and removed the certs.  Then reinstalled and I get the prompt but my apps are still faiing....

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

 

  

 

 

HI team.

we are using Fiddler core and wanted to have a small UI for it. wanted to check if Fiddler Core works with MAUI for mac and if there is some documentation. currently we are able to run it is net 6 but not in MAUI

also if there is any other technology that can be used apart from MAUI then it would also help

 

Thanks

I searched the web and found the .NET 'File.Open' instruction, but I have not been able to successfully use it in my script.

I am looking for something like this...

var content = File.Open('path/filename.txt');

This code is just an example, it does not work.

Thank you!

I am using the following code to serve a local HTML file when the URL of a web request contains a certain keyword.


Instead of a local file, is it possible for Fiddler to reply with a web page hosted on a remote server? Something like this...


Thank you!

The live traffic pane is showing a spinning animation as if it is loading something. It keeps going like this in a loop.

Please see attached image.

I use fiddler can capture most of the traffic , such as:

https://freetestdata.com/wp-content/uploads/2022/02/Free_Test_Data_7MB_MP4.mp4

in the console of the chrome, I can see the media size , and can capture it in fiddler;

but I can't capture the video in web.telegram.org/z/ or  web.telegram.org/k/ , in the console of chrome it shows serviceworker and I can't see the size of the media; The video can play , why can't capture it? How does the video stream send request and come back from the site?

Can I capture the video in telegram ? or save the video stream?

Hello,

where can I find all the possible prefs for Fiddler? I found a lot in a random ebook, but is there a documentation or source code where a list of all of them can be found? E.g. I know there's fiddler.config.path.captures, but is there one for the  CustomRules.js or just the whole Documents folder in general?

Regards

Any plans to add HTTP/2 support to Fiddler?

Hello,

I am using Fiddler Everywhere and would like to do automated testing. 

I found this on your blog:  https://www.telerik.com/blogs/api-testing-with-telerik-fiddler#disqus_thread 

 However, I do not have the "API Test" tab.  I would appreciate any help you can give me. 

 

Thank you
