Are there equivalent instructions to https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/UseFiddlerAsReverseProxy for Fiddler Everywhere?

I have enabled "Allow remote computers to connect".  I tried setting up an Auto Responder rule with a match condition of http://localhost:8866 and an Action of http://localhost:80.  However, I am getting a ERR_TOO_MANY_REDIRECTS in chrome.

    Currently (version 1.5.1), Fiddler Everywhere doesn't support working as a reverse proxy. I am marking this one as a feature request (and moving the topic to the FR forum section).

    Perhaps a checkbox in the confirmation dialog "are you sure you want to add the rca to your user" could have a checkbox like 'also add to the Local Machine store".

    Applies to Fiddler Everywhere and, more importantly for me, to Fiddler Everywhere Reporter.

    In my use case, I need the cert there as well to get traffic from a process that runs as a service.

    As things stand, I need to (instruct non-technical end users) to export the cert and manually add it to the Local Machine store and I would rather it were simpler.

    It appears that I need to add new columns for "VIA" and "SERVER" with each new recorded HAR session that I open. 

    Is there a way to set these extra two columns to always appear in my defaults?

    I am looking for a way to capture traffic from a machine and replay it later to simulate live load. I can see that I can capture the traffic and export it as curl script, but what it's missing the the times or the delays between the curl requests. This means that if I capture the traffic for 8 hours and then replay it, it'll be replayed all consecutively without delays which isn't simulating live load.

    Does anyone know a way to do what I need?

      Hey Nathan026,

      Thanks for posting your issue! 

      This sounds like a legit feature request that the team will triage. I am marking this one as an FR to be taken after the team triage meetings.

      An example scenario is using Fiddler to redirect a web application to use a locally running API instead of the server API. The web application needs CORS support on the API and the locally running API cannot provide such. 

      This is where the ability to simulate CORS support would come in handy.

        Colleagues, please add an essential feature of Fiddler Classic called Automatic breakpoints

         

        I'm sure that a bunch of people will migrate to Fiddler Everywhere if you implement this

         

        Thnx

        Fiddler for Windows allowed you to add custom columns to Web Sessions list. 

        Fiddler Everywhere needs this option so I can add in a column to show the IP address of the server being connected to.

        Can these methods be added into Fiddler Everywhere:

        1. https://docs.telerik.com/fiddler/knowledgebase/fiddlerscript/addcolumns
        2. https://docs.telerik.com/fiddler/Observe-Traffic/Tasks/ConfigureColumns

        Currently, Fiddler Everywhere capture every https traffic. Sometime, decrypt all https traffic are inconvenience and totally make the network broken (eg: Android 7+ devices). Please add this feature of Fiddler Classic.

        Hi, I have posted a question before the forum moved and did not get an answer to my latest question. https://community.getfiddler.com/support/discussions/topics/12000028910

        I have confirmed that unchecking selected parameters in the "headers" tab works correctly.

        But I have problems with unchecking the "body" tab. 


        I set my header's "Content-Type" to "application/x-www-form-urlencoded", 

        I put a key / value parameter in the body, and I send a request.

        After, I uncheck the parameter in the Body tab and I execute the request but still appears on the inspector.


        The problem persists even after the recent update. 

        Please check!

        Hi.

        When I try to trusst the fiddler root certifficate, I get the message "not successfull" and see a line like this in the logfile:

        [2021-03-01 16:29:48:866] [Information] [Fiddler] Error when trying to check if certificate is trusted: '.', hexadecimal value 0x00, is an invalid character. Line 304, position 38.

        I also tried to trust the certificate by hand via the keyring utility.

        What can I try?

        Thanks.

        I am trying to login to fiddler anywhere on Ubuntu.  But since the system is behind proxy, while logging into proxy, i get network error.

        I have configured the proxy in env variables as well as network settings >proxy, but it does not work.

        Please provide a way to configure the corporate proxy for fiddler everywhere before login

        Simple as that: fiddler everywhere does not capture traffic to localhost, 172.0.0.1 AND when you insert your local address, it captures your request only to return that "

        [Fiddler] DNS Lookup for "www.192.168.0.18" failed. System.Net.Internals.SocketExceptionFactory+ExtendedSocketException Device not configured

        "...

         

        MAC OSX, using safari.

        Other address are captured as expected

        I'm running on an Ubuntu 18.04 server. using VNC via gdm3 (gnome) display manager.

        The first time I tried to run progress-telerik-fiddler.AppImage, it brought up a dialog asking if I wanted to integrate with VNC and install a desktop icon, to which I answered yes.

        The window then closed, and each time I try to run progress-telerik-fiddler.AppImage again, nothing at all happens, as follows:

        wxr-xr-x 1 root root 113958410 Mar 25 14:15 progress-telerik-fiddler.AppImage
        root@cupertino:/nethome/osmolyar/fiddler#

        There is no desktop icon, log, or anything.

        Currently Fiddler Everywhere does not list anywhere how long it took to receive response (basic timings). Would be useful to expose that as a column, or add somewhere else in UI, at least in Request/Response info. Customising columns would help

        2 BIG Issues are present.

        First of all, I don't have an INTERNET connection any more after closing FIDDLER it has to be always running!

        Second issue Fiddler is working properly ONLY on the first Start. If  closing it and opening it again it's not working at all.

        FIX this ASAP

        In Fiddler (and in applications such as Wireshark) it's easy to collapse / switch between different protocols, headers and such.

        In the Fiddler everywhere version - you get the entire request/response as a single text block.

        It would be great to switch between protocols / collapse the parts you care less about and in general have better controls.
