Hiding CONNECT TunnelsOne of the first things you will notice while capturing HTTPS traffic with Fiddler Everywhere (or with other HTTPS proxies) is the presence of multiple HTTP sessions utilizing the CONNECT method. These are the so-called CONNECT Tunnels that the client applications configured to go through the Fiddler proxy are sending to establish a two-way connection.The CONNECT tunnels are used by the Fiddler proxy so that it knows where the requests should be directed—otherwise, the connection will be encrypted and Fiddler won't be able to direct the request to its target. While the CONNECT Tunnels are crucial for the proper work of an intermediate HTTPS proxy, they bear little information that can be used for web debugging and could cause an additional distraction while handling large portions of captured traffic.With Fiddler Everywhere, you can easily hide the CONNECT Tunnels so that you can see and concentrate only on the sessions that matter.Creating a "Hide CONNECT Tunnels" RuleThis example shows how to create a rule named "Hide CONNECT Tunnels" that hides all requests made with HTTP method CONNECT (also known as proxy CONNECT Tunnels).Create a "Hide CONNECT Tunnels" rule that sets the following matching conditions and actions through the Rules Builder.Create a matching condition that uses the "When all these conditions are met any number of times" pattern. Match by a Method that contains CONNECT as a string.Create a Do Not Show action.The Do Not Show action is final. No other action or active rule placed lower in the Rules list will be executed.This sample Fiddler rule hides all HTTP sessions that use the CONNECT method.Once the rule is created, enable the Rules tab, toggle the rule switch, and start capturing traffic.Download a ready-to-use "Hide CONNECT Tunnels" rule as a FARX file, which you can import through the Rules toolbar.See AlsoLearn more about the Rules functionality in Fiddler Everywhere here...Learn more about all rules presets in Fiddler Everywhere here...Learn more on how to organize your rules here...Learn more about the matching conditions here...Learn more about the supported actions here...Learn more about final and non-final rules here...Learn more about using breakpoints here...

The time has come for Fiddler to say goodbye to .NET 3.5. Our usage statistics currently show that less than 3% of our users are using .NET 3.5, and so we can no longer justify the effort needed to keep all new Fiddler versions running on .NET 3.5. We are still going to keep the most recent (at the time of writing) .NET 3.5 version in the Fiddler installer, and it will be automatically chosen for installation on machines that have no higher version of .NET installed. While you're welcome to keep using it, this version is not going to get updated from this point on. As time passes it is going to get less and less useful, and at some point in the future we will remove it completely. So, to sum up, in order to get updates to Fiddler from now on one should have at least .NET 4.0 installed. .NET 4.0 replaces .NET 3.5 as the minimal supported .NET version for Fiddler. FiddlerCore FiddlerCore will follow suit with Fiddler. The .NET 2.0 and .NET 3.5 builds will remain in the installer but will cease to get updates. The .NET 4.0 framework is going to be the lowest .NET version that will continue to receive FiddlerCore updates. Fiddler Add-ons At present the vast majority of Fiddler add-ons are compiled against .NET 3.5. They will keep on working on the new versions of Fiddler the same way they work on Fiddler for .NET 4.0 now. We will release .NET 4.0 versions of the add-ons that we maintain since it is now safe to do that. All add on creators are welcome to do that, too, and benefit from the features offered by .NET 4.0. In the future we will remove the dependency between the add-ons .NET version and the. Fiddler Everywhere v5.4.1 - Fiddler Everywhere release note in detail.

Answered on 12 Jan 2024, 08:04 AM As you have found, many of the Apple applications use certificate pinning. This means that the applications reject Fiddler Everywhere's certificate, so they cannot be decrypted. There's no legal way to bypass certificate pinning of those applications.When you use "Do not decrypt" rule in Fiddler Everywhere, the app just establishes the required tunnel and does not interfer with it. So, the client application (like "Find My") first sends a CONNECT request to Fiddler Everywhere. Due to security rules, the CONNECT request contains only the host for the request. At this point Fiddler Everywhere detects it should not decrypt the traffic to this host, so it established the required tunnels with the server and then just transfers the data without touching it. That is the reason why you cannot see the full URLs - this is by design the way CONNECT methods work - the client sends just information about the server for which it needs connection. You can find more information about CONNECT tunnels in the official RFC: So, in short - when using proxy, there's no way to get the full URLs called by applications using certificate pinning.Regards, Rosen Vladimirov Progress Telerik

It is safe to trust this certificate, BUT the implications are that you will not see any genuine certificate errors from websites, so you should keep Fiddler closed when you're not using it, and you should remove the certificate if you stop playing Neopets games.Fiddler seems to

Answered on 17 Jul 2014, 12:35 AM Hi, Stephen--I don't really understand your question. Fiddler is non-malicious, if that's what you're asking. Generally speaking, Fiddler shows traffic from your local computer only, not from "embedded devices" so it sounds like maybe you've set some other configuration? If you were to run Fiddler on a public IP and allow arbitrary connections, then Fiddler could serve as a proxy for anyone who chose to use your IP as a proxy, but you'd see their traffic inside Fiddler itself.If you have a PCAP of the traffic in question, please feel to email it to me using Help > Send Feedback inside Fiddler and I'll have a look upon my return to the office.Regards, Eric Lawrence TelerikCheck out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
