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

Is there any way possible to get your Public IP address within Fiddler Scripts (ScriptEditor in Customize Rules)? I attempted to use certain methods that you could do using C# (translated to Script language). I also thought that maybe It was possible to execute another script file (like powershell file) that could return a value within Fiddler Scripts... but so far could not find any way of retrieving public IP

I have a device that broadcasts a "discovery" packet to port 5556 and would like to capture that.  How do i go about doing so?

 

I have tried to run code and output log messages from OnWebSocketMessage() and OnBeforeResponse() but its not being apparently executed and no messages are in Log tab at all... so it just seems like its not even executing script file
