Hi, when I inspect grpc traffic and use the protobuf file to see the data as json, the viewer field (textbox?) is slightly hidden behind the status bar at the bottom (screenshot attached). It loses 2 lines.

I fire up Fiddler Everywhere on my Mac. Generally, it appears to do nothing.

In further detail, "Stream" and "Decode" can be toggled, but otherwise do nothing. The connections icon has a hover-over describing my host and states I have a network connection. The help icon goes to the very limited documentation via browser. The settings icon pops open the settings dialog, which does appear to save changes, but not impact the "nothing" being done by the application. The capture button and inspectors button appear to do nothing. The main viewing area states "No records available." The area to the right of the main area states "Please, select a single Web Session to inspect." And that is it.

Either I'm doing (or not doing) something dumb, or it just isn't working for me. Any help would be appreciated :)

Mac specs: High Sierra 10.13.6, 2.6GHz i7, 16 GB memory

I have 3 rules. Please check the images for detail how the rules define and their order of execution.

If I understand correctly, "Non-Final-After" rule must not be executed in this case due to "Final" rule contain a final action (Manual response).

But you can see, "non-final-after" header is added to response.

I am not sure if it's a bug or intended behavior.

Please take a look. Thanks.

Hello,

I would like to know how the internal logic for rules with multiple conditions works.

For example, let's say we have 2 conditions and a rule will be matched if all conditions are met:

  1. URL contains 'example.com'
  2. Response Body contains 'string'
  • Are the conditions checked in any particular order (i.e. URL is checked first)?
  • What happens if the first condition fails, does it stop and not check for the second condition?

Thanks

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!

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.

Im using MacOS Sierra 10.12.5

 

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

 

very very critical

Summary:

When I toggle the 'Live Traffic (Capturing)', mac prompts for a password. When this prompt is canceled by the user (no password entered) the toggle incorrectly toggles to off/on.

 

Steps to Reproduce:

1. Fiddler Everywhere open on a Mac

2. Toggle 'Live Traffic (Capturing)'

3. Select 'Cancel'

4. Notice Toggle changes state and the state of the Capturing does not change. 

Expected Result: The 'Live Traffic (Capturing)' toggle does not change state if the mac users permissions are not accepted. 

 

Observed Result: The 'Live Traffic (Capturing)' toggle changes state if the mac users permissions are not accepted.

I installed Fiddler Everywhere on Fedora 31. Clicking "View full response" for any response opens a pop-up window which is reasonably sized, but the content of which is a scrollable area about one line high at the top of the window and there is no obvious way to expand it to see more than one line of the response. Screenshot attached.

While inspecting requests where Content-Length > 3000, only 3000 characters of the request body gets displayed in both Raw and Text views. When I copy the whole contents of the selectable area (CMD + A, CMD + C) and paste it into a text editor, it seems like there is a 'View full request...' text somewhere which does not show up. I remember this button from previous versions. 

OS : macOS Mojave Version 10.14.6

A sample HTML with dummy form to reproduce the bug and recorded session is attached.

Latest version of Fiddler (v0.10.0) and Android Emulator is not proxying the connections properly.

I have Fiddler Everywhere running and know it is working when I can send requests through Postman and see them show up in Fiddler properly.

However, if I set up the Android Emulator through Android Studio, and set the proxy to be Fiddler, connections do not fully reach the backend service I am sending requests to. All that shows up in Fiddler is

REQUEST

CONNECT 192.168.5.7:5000 HTTP/1.1
Host: 192.168.5.7:5000

RESPONSE

HTTP/1.1 200 Connection Established
FiddlerGateway: Direct
StartTime: 16:12:05.141
Connection: close

The service is running on my local host machine (192.168.5.7) on port 5000.

If I close Fiddler and run charles-proxy, then set the Android Emulator to use that as the proxy, I see the full request, my service responds, and I see the response in Charles.

Steps to reproduce:

  1. Post a 69k request to a web api (encoded JSON data) via browser.
  2. Inspect request data in Text and Raw fields.
  3. Observe that the data is truncated in the middle of a property name (not a null char).

Example data posted (snippet with middle section excerpted):

valuesString=%7B%22request%22%3A%...oneTimeApproval%22%3A%22no%22%2C%22immediatePatientSaf

There is much more data that should occur after the property "immediatePatientSafety".  There does appear to possibly be additional fields presented in the Web Form inspector although some of the values are truncated and have an ellipsis (...) following those lines, so I believe that the tool is capturing the data but will not make it visible or available in the Text or Raw Inspectors.

No option exists to configure the amount of request data that is captured or to cause the Inspector to "show more" data.

I need to be able to see the full text request to troubleshoot an issue with the back-end application.

I need the data available in the Text or Raw inspector so that I can cut and paste it out for external processing and discussion with the developers.

I noted that a separate bug report has been issued for a missing "show more data" option on large response records.

Thanks,
Daniel

I'm unable to connect to "gateway.icloud.com" when Fiddler is open and decrypting HTTPS traffic.

This is Fiddler Everywhere 0.10.0 on macOS 10.15.5.

To reproduce:

Open Fiddler and make sure it's decrypting HTTPS traffic.

Open any browser and go to https://gateway.icloud.com/

Expected result: Page loads (it's blank. This is normal.)

What actually happens: fiddler.network.https> HTTPS handshake to gateway.icloud.com (for #820) failed. System.Security.Authentication.AuthenticationException The remote certificate is invalid according to the validation procedure.

 

Same thing happens on https://configuration.apple.com/

MacOs, Fiddler Everywhere 10, Cisco AnyConnect.

Here's the workflow...

In the morning, Cisco VPN isn't connected.  All traffic is blocked by design.  Attempt to start Fiddler Everywhere.  WON'T START because it can't login.  What is this new requirement to login?  If I don't start Fiddler before the VPN, no traffic ever logs.  If i don't start the VPN, Fiddler won't start.  A bit of a cartch-22, ya think?

Somehow I bypass the VPN (Don't tell corp security) and get logged-in.  Fiddler is up.  Start the VPN. Get some work done.  Shiny new UI!  Still can't drag-drop from inspector to composer?  Damn.

At some point the Fiddler login EXPIRES.  Why does it expire?  What do I even need a login for?  At this point ALL TRAFFIC fails, since Fiddler was the system proxy.  All work stops.  Now I need to stop Fiddler, Stop the VPN, attempt to start Fiddler again....oh wait, can't login because the VPN is down...  here we go again.

This is all a serious waste of time.  I can see registering Fiddler so you know who your users are.  What's with the REQUIREMENT to have a login, and why does it expire?  It kinda makes Fiddler useless.

Please remove the requirement to login to an account before being able to use Fiddler Everywhere.

 

Thanks,

Sean
