I am using NHtmlUnit on Windows 10 which is a headless browser Javascript engine which I've downloaded from Nuget.  NHtmlUnit allows me to request and download webpages using a standard Url e.g. http://someurl.co.uk but I cannot seem to see these requests appearing in Fiddler (Classic).  Have I configured Fiddler incorrectly? Or because NHtmlUnit IS a headless browser I am never going to see them?  Grateful for any help - thanks

fiddler打开就崩溃

Hi, 

I'm trying to save streaming to disk file. However, the stream sometimes is interrupted by unstable internet connection. Then I got a 504 error saying ReadResponse() failed:The server did not return a complete response for this request.

But I can see some bytes are already downloaded. Is there any way to save the downloaded bytes to a file?

I tried the OnBeforeResponse() event in FiddlerScript. But the event is not fired when 504 error occurs.

 

Best regards,

 

Hi

I have set the prefs very high (prefs set fiddler.importexport.HTTPArchiveJSON.MaxTextBodyLength 600000000000) but fiddler is still omiting response body.

The current issue is with a request with Response Content-Length: 2175586 and it is being omitted. Can you tell me how to make fiddler not use a limit at all.

Hello. I intend to use the program without stopping long enough. I express concern that Log may worsen the program's performance. I want to disable it, how do I do this?

So I have a C# that follows this tutorial + my own code in Class1.cs. Fiddler Extension... When doing So, I create it, build my project. It gives me .exe and all of the other goodies but, does not give me the .dll I need to import it into scripts folder. These are the files I get when my project is built:... So What am I doing wrong here?

Before I reinstall windows, I used Fiddler Everywhere to capture https normally, but after reinstalling windows, it can't show HTTPS traffic.

I had the same setup with Fiddler Everywhere before reinstalling windows.

The app I'm trying to debug network traffic shows an error when I enter into the app.

Hello,

For the extension I work on it might happen that I need to recognize a HTTP request to a domain that does not exist. However if such a session ends with "HTTP/1.1 502 Fiddler - DNS Lookup Failed" in the Response Header, my extension is not triggered.

Such responses neither trigger the

AutoTamperResponseBefore(Session oSession)

method, nor the

OnPeekAtResponseHeaders(Session oSession)

method. My question is, what can I do here to notice such cases with my extension?

And another question, which other cases should I be aware of that don't cause a proper response?

I have installed and reinstalled fiddler but when I start fiddler I the initial checkup.aspx load in it but then it never gets any more traffic.  I have tried multiple browsers but I never get any traffic.

I'm I missing a setting?

Hello,

I am very new to this program, I was wondering if it were at all possible for fiddler to only monitor traffic of ONE application only.

So that the fiddler only monitors one particular program/excutable, and everything else does NOT go through the proxy?

I tried to use OnBeforeRequest function: listed here - https://docs.telerik.com/fiddler/configure-fiddler/tasks/decrypthttps#skip-traffic-decryption-for-an-application but its still going though the proxy, the proxy is just chosing not to decrypt it, I basically want all to blacklist everything and whitelist X application to go through fiddler, and decrypt the HTTPS.
