Hi guys,

I'm using different proxies for each browser, let's say 5 different proxies/IPs.

The question is: How to make the fiddler classic capture the traffic (requests/responses) from all the browsers? It means that it should read the traffic from 5 proxies at the same time.

Having updated Windows 10 to 11, fiddler will no longer launch. 

I've tried uninstalling/reinstalling, but see the same effect.

The application event log shows the following pair of entries each time:

Faulting application name: Fiddler.exe, version: 0.0.0.0, time stamp: 0x00000000

Bright ideas?

i know how to retry a request on normal 500 error or when it give error in OnReturningError chain

but the problem is the error with HTTP/1.1 0 FIDDLER GENERATED - RESPONSE DATA WAS MISSING and response code 0 wont retry what chain exactly handle this error ?

 

How to disable the echo service?

After I download the cer from the http://fiddlerip:port/ , I do not need the echo service anymore. And for security, I need just keep proxy func, and shutdown the echo service.

After search whole google, can not find clue.

Anyone can help?

Thanks

I have a website that sent an error message: "err_connection_aborted" when I connect to it using HTTPS.

When I have Fiddler active it works perfectly, so I'm not really able to debug the issue.

I've been fighting this error for several days... should be very easy, it's just a webpage under HTTPS. It works OK in HTTP, but something goes wrong with HTTPS.

 

Thanks!

I am a new Fiddler classic user on Windows 10.  I can easily monitor http(s) requests of my browsers such as Chrome or Microsoft Edge. However, no http(s) requests are seen from my Application "Ubuntu on Windows". I have checked it (exemted) in WinConfig toolbar. What could be the problem here. Thanks in advance!

I ran a trace from a handheld device to a server in a data center. In short, the trace reads:

- ClientConnected: 12:44:55

- ServerConnected: 12:50:39

- ServerBeginResponse: 12:50:51

Does this mean that the Server spent 12 seconds data processing before responding?

 

 

 

this is a feature proposal. With comments made by user, we can easily trace back the session after saving lots of sessions.

The url captured by fiddler can send instructions through the software's own composer and return the correct json file.

However, the correct result cannot be obtained under the requests of python, and it will prompt:

{"Message":"Cannot convert object of type \u0027System.String\u0027 to type \u0027Carpa.Web.Script.HashObject\u0027","StackTrace":" in Carpa.Web.Ajax.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer)\r\n at Carpa.Web.Ajax.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)\r\n at Carpa.Web.Ajax.AjaxHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary `2 rawParams)\r\n at Carpa.Web.Ajax.AjaxHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

The code is as follows: ("..." means omitted information, the headers are consistent with the information in the fiddler software)

from urllib import response
import requests
import json
url = "http://......Web.Script.DataService.ajax/GetPagerDataEx"
headers = {
"Accept":"*/*",
"Referer":"...",
"Accept-Language":"zh-Hans-CN,zh-Hans;q=0.8,en-US;q=0.5,en;q=0.2",
"Content-Length":"...",
"Content-Type":"application/json;charset=utf-8",
"X-ClientType":"SLJson",
"X-JSONFormat":"true",
"Accept-Encoding":"gzip,deflate",
"User-Agent":"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.2; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; Tablet PC 2.0)",
"Host":"...",
"Pragma":"no-cache",
"Cookie": "...",
"Connection": "keep-alive"
}
data = {
"pagerId":"$......$ptypeDataSource",
"queryParams":"null",
"orders":"null",
"filter":"null",
"first":"...",
"count":"...",
"isFirst":"false"
}
data = json.dumps(data)
response = requests.post(url=url,data=data,headers=headers)
content = response.text
print(content)

Hope that helps, thanks!
