Hi, first of all, I must warn you that I am a beginner in general computing so if you can help me with a solution, please make it basic. Thanks.

When I try to install Fiddler Classic, halfway through the download, a command line will pop up.

After about 2-5 seconds, the command line will close and a warning message will appear.

I cannot copy and paste the command line popup as it closes too quickly, but I do have a screenshot of it.

The warning message cannot be selected or copied so I will also attach a screenshot of that too.

As the warning says, I have added the installation directory to the PATH environment variable, but it does nothing. 

I may be doing something wrong, but as a non-advanced computer guy, I can't tell.

I have tried to install Fiddler Classic on another computer and no warning or command line popped up, but for reasons, I cannot use that specific laptop. However, this means it is on my end. I have tried reinstalling many times before, to no avail.

Help would be welcome.

Thanks in advance,

Bobby

With Firefox v101 I can no longer decrypt HTTPS with Fiddler Classic.

I reset Fiddler's Root Certificate multiple times to no avail. 

When the same is tested in MS Edge, no problem

I'm getting below error while opening fiddler classic

Hi,

I'm trying to find the way to read the next string after finding given text in response html.

It will contain fe. "someNum is: 1234" but the number will be different in every response.

My question is, how to grab the number, which sits in the string, when finding begginnig of the string which is "someNum is:"

 
if (oSession.oResponse.headers.ExistsAndContains("Content-Type", "html") {
    oSession.utilDecodeResponse();
    oSession.utilFindInResponse("someNum is:");
    var = <here I want to put the value, whatever it is>;
    oSession.Log.LogString(var);
}

Thanks.

Hello all,

I have a request parameter (guiStatusGZ) which is compressed and I want to uncompress it to edit the data before displaying in the UI via response.

Kind regards,

Hi,

I have run a Nodejs application on localhost, which receives requests from an external DNS and do some actions as a result. In order to be able to capture the incoming traffic from the Internet to my localhost server, I have set a reverse proxy using Fiddler classic docs, which works fine and I can see any request that is going to my server. However, inside my application, there are some API calls, which are not local and they are accessible through the Internet. The problem is that Fiddler doesn't capture any outgoing traffic from my app to the Internet. All of those API calls work fine and are successful. I have checked whole the Internet and unfortunately couldn't find any useful solution. I have also added some screenshots from important configs of Fiddler. I also run my server on 127.0.0.1:3000. I hope you can address my problem. Thanks!

Currently Fiddler Classic supports WebView using old IE control that makes low compatibility for modern web. and I need to see some request using WebView, but it doesn't show me the 'correct' view, for modern HTML. I think using WebView2 for it is good idea for modern web.

(sorry for bad english)

Why would a https page work successfully when running a fiddler capture but then when i close fiddler, the page no longer works?
I have the decrypt https traffic options selected 

How would i get that to stop so i can capture why page does not work under normal circumstances? 

Hello all,

I have seen various threads about this topic but although I followed all the recommendations, nothing had a successful result. I have installed fiddler on my new Win10 laptop. Hotspot is created through NoWifi windows app since the driver does not directly support hotspot. Mobile is connecting normally to the hotspot and has access to internet without a problem (sharing my ethernet with the mobile hotspot). When I modify the wifi connection on the mobile to give the ip and port for the fiddler proxy, the mobile has no access to the internet any more.

Fiddler has:

• Enabled Capture HTTPS CONNECTs
• Enabled Decrypt HTTPs traffic
• Enabled Allow remote computers to connect

And has been restarted after the settings have configured.

When I connect to the wifi with the mobile, I try to reach the ipv4.fiddler:8888/ page but I get Site can't be reached...

I have also tried to change the certificate generator to BouncyCastle but this did not work either.

Any ideas would be greatly appreciated.

Thank you very much,

Haris

Hello,

Does Fiddler Everywhere support websockets?

If it does how can I enable it?

Thank you in advance.
