Hi,

 

is http://ipv4.fiddler:8888/ down?

Hi,

I'm trying Fiddler with an electron application. I don't see any of the http.get requests made from my electron application to remote servers. Is there some special setup I need to do? I'm on Windows 10.

Many thanks

Why fiddler cant dycrypt traffic ?

-

Hello

I want to capture the requests made by a website but they are not all displayed in Fiddler.

In Chrome Network inspector, every request which is not displayed in Fiddler has the attribute "memory cache" or "disk cache" in "Size" column.

How to capture them ?

This is basically my first attempt at writing an inspector, and it is for a websocket whose messages are compressed on the transport level, so in order to decompress (for example) message #5, it needs to be decompressed with a compression state that has already been fed messages #1 thru #4. (i.e., it's impossible to inspect any message given just that particular payload's body). I read the IWSMInspector interface is used for inspecting websockets but I see no obvious way to accomplish what I want here. Previously I've just been proxying the websocket through fiddler to a separate little script that handles decompression but I would much rather be able to just have everything contained within fiddler. If it simplifies anything, the messages of concern are only from the server to client direction.

I have used FiddlerCore4.dll to capture the url. But I have the following problem that I don't understand why the error is.
I use fiddler capture request of a program. That program sends 2 urls. But the first url is captured by fiddler. The second url cannot be captured. I copied that 2nd url and pasted it in my web browser and fiddler caught it
Now how do I get the 2nd url from that software program to send?

I have sent a video of my test demo process. You can watch to understand the problem. At the same time, I have attached my 2 programs that I am testing in the video

Hello,

As soon as I start Fiddler, any attempt to connect to a secure web page fails with the message "Your connection is not private" in my web browser.

What's going on?

 Thanks

can you confirm Log4j or Log4j2 being used in "Progress Software Telerik Fiddler 4"

Hi,

I have been using HTTPS decryption in Windows Fiddler for years, to inspect the traffic to and from my app.
And it has been working perfectly on both my Samsung phone with Android 12 and my iPhone 6 Plus with iOS 12.5.5.

Recently I got an iPhone 11 with iOS 15.1, and find myself completely unable to get it to work 😢

Because I know, that requirements for certificates have been strengthened in recent versions of iOS, I have now ended up "resetting" the certificate in Fiddler and creating a new root certificate. I have successfully removed the old certificates and installed the new Fiddler certificate on both the Samsung and the iPhone 6 Plus, following the Capture Traffic from iOS Device guide, and everything works like a charm.

On the iPhone 11, I have also installed the certificate:

And I have enabled full trust for it:

And yet, if I try to visit e.g. https://google.com/ in Safari, I get an error message telling me that "This Connection Is Not Private":

And if I click "view the certificate", it shows that the google.com certificate, issued under the Fiddler root, is "Not Trusted" - with no indication as to why???
