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:

static function OnBeforeRequest(oSession: Session) {
    if (oSession.HTTPMethodIs("POST")) {
        var cliEnc = System.Text.Encoding.GetEncoding("utf-8");
        var srvEnc = System.Text.Encoding.GetEncoding("shift_jis"); // "shift_jis" is still often used in Japan...
        oSession.requestBodyBytes = System.Text.Encoding.Convert(cliEnc, srvEnc, oSession.requestBodyBytes);
        oSession.oRequest["Content-Length"] = oSession.requestBodyBytes.Length;
    }
}

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...

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

Hello,

 

first I want to say thank you for this fantastic and very useful tool. But I have a question regarding switching between multiple interfaces on my

PC with FiddlerApplication.Prefs.SetStringPref(): Each time I send a Http POST Request after changing my IP with FiddlerApplication.Prefs.SetStringPref()

it works, but if I send a GET Request my IP is not changing. Can you help me please?

 

Thank You!
