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

Alternatively, you can copy/paste the file contents into Fiddler->Rules->Customize rules (erase everything in there first), and hit Ctrl+S to save. You should hear a slight ding.In Fiddler go to Tools -> Options -> HTTPS.Enable:Capture HTTPS CONNECTsDecrypt HTTPS TrafficIgnore Server Certificate Errors.Click Actions->Trust Root Certificate. This will make other browsers (like Chrome), and Windows apps such as Discord, also trust the proxy (Fiddler). This isn't strictly necessary, but if it's not done, you won't be able to use Chrome/Discord/Etc while Fiddler is running and intercepting traffic.Important: Add exclusions to your proxy: In Fiddler, go to Tools->Options->Connections, and add the following into the "Bypass URLs that begin with..." field:;discord.com; discordapp.com; netflix.com; *.discord.com; *.discordapp.com; *.netflix.com; *.discordapp.net; discordapp.net; *.google.com; google.com; *.gmail.com; gmail.com; *.youtube.com; *.gstatic.com; *.cloudflare.com; *.googleapis.com; *.jquery.com; *.googlevideo.com; support.neopets.comDownload the neopets folder in this projectFind fiddler installation path (usually C:\Users\YOUR_USERNAME\AppData\Local\Programs\Fiddler or C:\Program Files\Fiddler), create a folder named "neopets" and extract the downloaded neopets.zip files into it.

You can remove this certificate later via Windows Certificate Manager (certmgr.msc->Trusted Root Certification Authorities->Certificates). The name of the certificate is DO_NOT_TRUST so that you're well aware it's a local certificate, and not from a trusted Certificate Authority (CA). 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

Three Little Pigs is a 1933 Silly Symphony animated short film based on the classic fairy tale about a trio of pig brothers, who build their houses out of straw, sticks, and bricks to protect themselves from the Big Bad Wolf. The short won the 1934 Academy Award for Best Animated Short Film. In 1994, it was voted #11 of the 50 Greatest Cartoons of all time by members of the animation field. In 2007, Three Little Pigs was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".Plot[]Fifer Pig, Fiddler Pig and Practical Pig are three brothers who build their own houses with bricks, sticks and straw respectively. All three of them play a different kind of musical instrument – Fifer Pig "toots his flute, doesn't give a hoot and plays around all day," Fiddler Pig "with a hey diddle diddle, plays on his fiddle and dances all kinds of jigs" and Practical Pig plays the piano. Fifer and Fiddler build their straw and stick houses with much ease and have fun all day. Practical, on the other hand, "has no chance to sing and dance for work and play don't mix," focusing on building his strong brick house, but his two brothers poke fun at him. An angry Practical warns them "You can play and laugh and fiddle. Don't think you can make me sore. I'll be safe and you'll be sorry when the Wolf comes through your door!" Fifer and Fiddler ignore him and continue to play, singing the now famous song "Who's Afraid of the Big Bad Wolf?".As they are singing, the Big Bad Wolf really comes by, and blows Fifer's house down (except for the roof). Fifer manages to escape and hides at Fiddler's house. The wolf pretends to give up and go home, but returns disguised as an innocent sheep. The pigs see through the disguise ("Not by the hair of our chinny-chin-chin! You can't fool us with that old sheep skin!"), whereupon the Wolf blows Fiddler's house down (except for the door). The two pigs manage to escape and hide at Practical's house. The Wolf arrives disguised as a Fuller Brush man to trick the pigs into letting him in, but fails. When the Wolf tries to blow down the house of Practical, blowing off his suspenders and pants in the

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
