Hey guys,

I know there are some other posts on this. So the setup I've got which is mostly working is with:

• TLS Decrpytion
• Streaming mode enabled
• Loopback Exemption for Mail and Calendar

The odd thing is that if I close Mail (and end the process since it's a background app) and start it up, then Fiddler will capture it fine. The traffic is visible, and the app will operate correctly (sync, send etc.)

However, after some time period, the capturing will stop, and then the app will stop being able to communicate as well. Even if I stop overall Fiddler capture, this will not fix the problem, nor will ending Fiddler (cancelling it's proxy), only nuking the Mail App and restarting it corrects the issue once this occurs. If I don't run Fiddler at all, it doesn't run into this problem, and always connects fine.

Seems like this probably isn't a direct Fiddler issue, I wondered if anyone had any ideas about why it might cease functioning after a time?

Cheers,

Mike

We have been using Fiddler in order to trouble shoot issues regarding the Distribution Functionality in SAP's EPM Add-in application. This worked fine with our Windows 7 platform. However, after an upgrade to Windows 10, we are no longer getting any trace/log information after logging into the EPM Add-in application.

 

Any assistance is appreciated?

Hi

I need send a specific request and use one parameter of its response to send another request.

Is it possible to do it? for like 100 times?

How should I start? Any example or tutorial?

Good afternoon! 

We're looking to use Fiddler for troubleshooting on-demand and want to be able to do some automated install/uninstall pushes.  Are there any silent or unattended options that can be used with this installer?  Or perhaps an MSI package rather than the provided EXE?  And once it's installed, is there a way to automatically configure some general parameters, like disabling the autocheck for updates and preventing the autoload of the website on first run as it's inaccessible from our environment anyhow?  Thank you for your assistance!!  :)

I have installed Fiddler certificate to my Android device. I see decrypted https traffic, but there are no websocket requests.What can be the reason of this problem?

what do the colors of the lines mean??

Web server host on remote box, I have fiddler set up with a Host filter to "Show only the following hosts" http://192.168.48.64:3005/;

Fiddler reports "Capturing" but no traffic is coming through, despite using and refreshing the webpage repeatedly. I've even used Postman to issue a simple login GET. While filter is active, all traffic is removed from feed. Only using "Help > Troubleshoot" reveals all traffic with strike through, but unfiltered traffic is better at that point because it lacks the strike through.

Switching Host filters to -No Host filter- and instead turning on Client Process "Show only traffic from" application, and using that application to generate traffic did work.

Using Google chrome and Postman to create traffic.

Progress Telerik Fiddler Web Debugger

1. Run a server side event server such as https://github.com/hemanth/sse-now
2. Open a page that connects to the server (below)

Result: Events are not received

Following the same steps while Fiddler is not capturing sessions, everything works as expected. Enabling streaming does not solve the issue.

Is this a bug in Fiddler or is there some way I configure Fiddler to handle this?
