Fiddler not displaying sessions

Question

Hi,

I've got the latest version of fiddler installed on 2 machines (v2.3.0), and on one machine it displays web sessions, and in the other it doesn't.

This is using IE and Firefox on Win7.

I have tried deleting my customrules.js and letting fiddler create a new one.

I know that the broken machine is indeed proxying traffic through fiddler, as I see the fiddler SSL cert when I go to HTTPS sites.

I have set the option at the bottom-left of the window to All Processes, Web Browser and Non-Browser to no avail. I just can't seem to get the sessions to display.

Any hints to where I should look to find out what's going wrong?

Thanks,

Kirk

Set the Status bar filter to "All Processes", check that the Process Filter in the toolbar isn't set, and examine the Filters tab to make sure that no rules are enabled. If you've written or set any Rules (see the menu) check those too.

Answer 2

In rough order of likelihood..

• Ensure File->Capture Traffic is checked (obviously).

• Ensure it says "All Processes" in the bottom left.

• Flick to the "Filters" tab and uncheck Use Filters (I always forget this..)

• Same goes for the "AutoResponder" tab.

• Click the "Process Filter" button on the toolbar once to make sure it's off.

• Go to Help->About Fiddler and compare the port number with IE->Options->Connections->Lan settings->Proxy server->Advanced

• If that fails, uncheck the following:

  Rules->Hide Image Requests
  Rules->Hide HTTPS Connects
  Rules->Hide 304s
  

• To eliminate anything in the rules script, go to Rules->Customize Rules and add the following line to the end of OnBeforeResponse():

  oSession.oFlags.Remove("ui-hide");
  

  (If that fixes it, something in your rules is setting oSession["ui-hide"])

If all that fails, go to the Fiddler group and post a question, you'll normally get a pretty quick response from Eric Lawrence himself.

simple..
