I can see traffic from Chrome and Firefox just fine, but I get nothing from IE.

It was previously working, a month or so ago, on IE10. I've tried re-installing Fiddler and IE10 (not at the same time).

It worked while I was on IE8 but I don't want to use IE8.

It didn't work on IE9, 10, or 11 today.

I've tried starting Fiddler as admin / elevated.

When I load the URI http://ipv4.fiddler:8888/ in firefox I see "Fiddler Echo Service..."

When I load the same URI in IE I get "this page can not be displayed..."

I can get it to work briefly by manually setting winINET proxy to 127.0.0.1:8888, (and when this setting is in place http://ipv4.fiddler:8888/ works too) but if I touch the "capture" button in Fiddler at all (as if to enable or disable, either way) it stops capturing and doesn't restart until I manually re-enter the winINET proxy setting.

This would be semi-OK but I need to chain to another upstream local proxy and as soon as I enable this Fiddler stops capturing again. I should note I use the same setup with the two proxy apps on another machine with no problem.

 I'm guessing *something* installed on this machine is preventing Fiddler from editing my winINET proxy setting, but I don't know what it could be. AFAIK I have all the same software on the other machine which is working nicely. Can you maybe suggest how I could go about tracking down the offending bit of software, if there is one?

thanks,

Hello, wondering this post is appropriate here. if its not please feel free to delete it.

I was using fiddler to find out the HTTP packets sent by Google Chrome. Just wondering if anyone has done this and knows the information inside the cookies that chrome stores? Does anyone know if I could get the device ID that chrome has assigned to my PC?

Thanks a lot!

I am trying to use Fiddler to decrypt and analyze https traffic on my computer, following the instructions here (http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/DecryptHTTPS).

When I choose "Decrypt HTTPS traffic," Fiddler prompts me to install the root certificate, and I do.  I also export the certificate to install in Firefox.

After installation, Firefox trusts the certificate, but Chrome & Internet Explorer do not trust it, and block all navigation.  When I open the windows certificate manager (certmgr.msc), the Fiddler certificate does not appear in the Trusted Root Authority store, even after I try to manually import it.

 Any tips?

Hello!

 I am sending REST Get request with Mule ESB 3.6.1 and there is a parameter to the query. However, if I use Fiddler (4.5.1.0) as proxy, the parameter is removed from the request. If I send the same request from Jmeter and use Fiddler as proxy, the parameter is present. If I dont use Fiddler as proxy in Mule, the parameter is still present.

I am writing a Fiddler extension which I would like to sign.  Unfortunately this is not possible because it seems Fiddler itself does not have a strong name, therefore my project cannot reference it.

 Has any thought been given to this?  Are there plans to sign Fiddler?

Hello,

i really like fiddler and the rich features of it , the only feature that i think is not effecient is the capture traffic option, yes, it does capture the traffic of some programs but not every single program, so for these programs i use httpdebugger which capture traffic from every single program that is using http or https but it's not rich in features as fiddler, so if you could improve the capture traffic and use the same technique the http debugger use (what ever it is) that would be appreciated

 examples  of the programs the fiddler doesn't capture their traffic

I am a Japanese user. I want to convert the char-set of request for a web application which supports only non-English char-set because UTF-8 is set as the char-set of POST body from Fiddler Script.

I wrote the following code but I was not able to change the char-set from UTF-8:

Is there the method to change the char-set of POST body?

At work we use fiddler heavily to be able to record and playback URLs and their content.  However, when an environment goes down, we have to go into our list, find the URLs we care about, drag them over to the autoresponder.  I was hoping I could write (or maybe something exists) that would automatically save given URLs to the autoresponder tab when they are hit, so if the environment goes down I could just go in and enable auto responses.  Thanks for any thoughts...

I am working on a java application and I get 404 error in fiddler for css files:

/webroot/adf/styles/cache/*-desktop-4le0gq-en-ltr-ie-cmp.css.

These files are not present in the specified location.IHow can i get rid of these errors in fiddler.

Note: The application works fine and there are no functionality issues because of this error

Hi there,

Thank you for a marvellous product!

I'm experimenting with AutoResponder, and have found that the "Match only once" option is effected by whatever was lasted cached...

For instance, if I have 2 basic rules defined, both with Match only once option checked, as follows:

1) If request matches... "sandbox", then respond with... "http://google.com"

2) If request matches... "sandbox", then respond with... "http://microsoft.com"

Then selecting Tools > Sandbox will continue to be redirected to http://google.com, and will not invoke the second rule until the cache is cleared by way of Tools > Clear WinINIT Cache...

Forgive me if this stupid question, but is there an option somewhere in Fiddler to tell AutoResponder to override the contents of the cache?

Many thanks!

Antonio
