Hello, I'm trying to output the HTTPVersion in FiddlerApplication.AfterSessionComplete,

but sites corresponding to HTTP/2 always show up as HTTP/1.1.

 

source code:

FiddlerApplication.AfterSessionComplete += delegate (Session session)
            {
               
                string httpVersion = session.oResponse.headers.HTTPVersion;
                Console.WriteLine($"HTTP Version: {httpVersion}");
            };

            CustomRootCert();

            FiddlerCoreStartupSettings startupSettings =
            new FiddlerCoreStartupSettingsBuilder()
             .ListenOnPort(9999)
             .RegisterAsSystemProxy()
             .DecryptSSL()
             .Build();
            
            FiddlerApplication.Startup(startupSettings);

I have tested using online unpkg https://nuget.telerik.com/v3/index.json and local file dir, Neither can be installed. The screenshot is as follows. Please help troubleshoot the problem.

Okay, so i'm not sure if this is in the right spot or not but here it goes.

 

I am using Fiddler Core in my C# program. In my program; I have several checkboxes and each checkbox sets utilreplaceinresponse; while this is all good; After the session is complete; I need to have Fiddler Block that same url from reloading unless the program is closed or cache is cleared. How can I achieve this?

I would like to suggest that Fiddler products be added to the Progress Control Panel to allow better management of updates and installations.

Hi, how would I in the BeforeRequest event return a file from the local computer?

This is related to FiddlerCore, and I'm trying to recreate the function of the Fiddler AutoResponder, to match a string and then respond with a file. Would BeforeRequest be the right thing?

I found this somewhere else on the forum: http://fiddler.wikidot.com/fiddlercore-autorespond

Hope someone has a bit more knowledge,

Thanks

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

Environment:

FiddlerCore: v5.0.1

.Net: v6.0

Issue:

I've written a fiddle script to send another request to get the necessary info to proxy the original request via FidderClassic. It works fine with the tls1.2 protocol. But when I try to use FiddlerCore to do the same thing, I got the 502 error again(the error occured when I use FiddlerClassic without tls1.2 protocol).

Is there any insights for this issue? Thanks

Environment:

FiddlerCore Version: v5.0.1

.Net Version: .net6.0

windows: win11 22h2

Issue

My requirement is when I get the specific request, I need to send another request to get some extra info and then modify some parameters of the original request. I wrote a fiddler script to achieve that and it works fine by Fiddler Classic when I set the TLS1.2 for Https options.

But when I try to use FiddlerCore to do the same thing, I got the 502 error.

I followed https://www.telerik.com/blogs/fiddler-and-modern-tls-versions to set the protocols of connection to support the tls1.2, but it doesn't work!!

Is there anyone can help me figure out what should I do to to resolve this issue
