Hi there,

I know we don't have a GUI option to filter bodies.

I was thinking about using OnDone for hiding/filtering them.

I just need a way to get the body and a way to block this.

 

 

I'm getting too many packets. I would like Fiddler to exclude packets that have no information valuable for my analysis.

I recently upgraded to Windows 10, and I love it so far. It appears that Cortana does not function fully for me though. I am running accountability software on my computer called X3Watch. It simply monitors all of this computer's network traffic and filters it through a proxy. Many of my previous Windows 8 (and now Windows 10) apps had to be "enabled" using Fiddler (See my link below for more info). If I click Cortana's search bar, I believe I should see several cards relating to weather, sports, etc. Right? Unfortunately, it's blank for me. All she says is "What's on your mind [name]?" If I watch the traffic in Fiddler, Cortana tries to connect to localhost:58084 via the URL /proactive?form=WNSBOX using the process searchui.exe, but unfortunately it results in an HTTP 502 error. Fiddler does not list it as a Loopback exempt app. Can anyone help? X3watch support was not helpful in solving this.

 

Also if I go into the Cortana Notebook > Settings and disable "Cortana can give you suggestions, ideas, reminders, alerts and more" it appears to show generic cars in the Cortana bar. If I switch it back, I get nothing. If I click on the Cortana "Ask me anything" search bar, it sits there doing nothing until eventually it says "Go ahead and tell me to do something. Interests aren't available at the moment."

The Fiddler documentation is poor in regard of configuring the Java RE or SDK to work with Fiddler and HTTPS. After some digging I found this article which helped me solve the problem:

http://codeketchup.blogspot.com/2014/03/how-to-use-eclipse-with-fiddler-step-by.html

It is important to read the comments too, as from the article it is not 100% clear what to do.

  • I have a Windows 7, 64-bit machine where launching Fiddler 5.0.20181.14850 hangs with a splash screen showing "Creating Proxy..."
  • I tried removing and reinstalling.  I tried rebooting.  I tried installing with and without Run as administrator.
  • Running Fiddler hangs if launched normally.  It launches successfully if launched with Run as administrator.
  • On the same machine, an older version of Fiddler successfully launched without Admin.
  • Is there some magic to get past "Creating Proxy..." when launched as non-Admin?
