Progress Teleferik Fiddler performs HTTP and HTTPS debugging, managing the traffic between the web and your end system. The program can be used to perform such tasks as web session manipulation and security testing.It comes wrapped in a decent looking interface, with nicely crafted menu icons, a simple left panel, and a large work area. It doesn't have any kind of skin themes, and the customization options are quite basic.Progress Teleferik Fiddler can cope with various user activities, from web testing to HTTP and HTTPS traffic recording. You can use it to edit web sessions by simply setting a breakpoint to pause the processing of the session and permit alteration of the response.Perform security testing by decrypting HTTPS traffic and modifying web application requests.It's also very useful when you need to debug traffic from PC, Mac, or Linux systems. You just have to ensure that the proper cookies, headers and cache directives are transferred between the client and server.Overall, Progress Telerik Fiddler is a good choice for testing and diagnosing web applications and websites, though sometimes it misses some server requests, as well as a web filtering option, and the price seems to be too high.

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

When you submit reports for Telerik Platform related issues, the support engineers are very likely to request a detailed Fiddler log to aid them in the investigation of the issue.IMPORTANT: When started, Fiddler captures all HTTP and HTTPS traffic, including some sensitive information. Do not share Fiddler logs outside of the private support communication channels (e.g., support tickets).SolutionDownload Fiddler from here and install it.Run Fiddler and go to Tools -> Fiddler Options.On the HTTPS page, verify that Capture HTTPS Connects is enabled.Verify that Decrypt HTTPS traffic is enabled with the ...from all processes option.Minimize Fiddler to tray.Replicate the reported issue.In Fiddler, go to File -> Save -> All Sessions and save the archive to disk.This will produce a SAZ file, which you will be able to archive and share with the Telerik Platform support personnel.NotesIf the produced Fiddler log doesn't contain HTTPS traffic records, [make sure that the Fiddler Root certificate is trusted on your machine]({% slug trust-fiddler-root-cert %}).See AlsoFiddler Documentation

This is a migrated thread and some comments may be shown as answers. ed asked on 21 Apr 2021, 08:26 AM Hello,Is it possible to capture localhost (client and server) websockets communication?In my case, in the client side I am using javascript code to connect to the websocket server, that it is started using java language.In fiddler I do not see anything...Regards,Ed 1 Answer, 1 is accepted answered on 23 Apr 2021, 01:11 PM Hello Ed,Yes, it is possible to capture websocket traffic with Fiddler Classic. I've attached a screenshot of the product where you can see the websocket communication between a Node.js server running on the localhost and a local webpage opened in the browser. In order to see the websocket traffic, you must ensure the requests sending from your client app respects the proxy set by Fiddler Classic. After that, just locate the request marked with the small WebSocket icon and double-click it.Hope this helps.Regards, Rosen Vladimirov Progress Telerik
