Identifying website performance issues using Fiddler

Hi guys

I wonder if someone could help me out with this. I'm looking into performance issues on a website https://collaborate.eversheds-sutherland.com (213.212.88.203). The issue is that every now and again within the site, various pages hang/time out, sometimes kicking out a logged in user back to the login screen.

There's no pattern in terms of time of the day, it happens completely randomly. The issue only occurs when users are connected to the office LAN. The website is hosted externally and works absolutely perfectly when on 4G or home Internet. The problem lies somewhere within the office LAN infrastructure.

My gut feeling was DNS or asynchronous routing. Yesterday, I started using Fiddler and came across a DNS failover error (please see attached).

My apologies for the amateur question but I'm extremely new to Fiddler. Would this DNS flag indicate an internal DNS issue or is this a red herring and should I continue down the routing avenue?

Any advice/suggestions would be greatly appreciated.

Regards

B

Unable to communicate with server

Hello,

I've been trying to debug some network issues of a .NET WinForms-based application, but when the "Decrypt HTTPS traffic" option is enabled in Fiddler (screenshot1), I always experience issues with the application (screenshot2). The "Decrypt HTTPS traffic" is working for HTTPS traffic handled by web-browsers, but it does not work at all with this Windows program, despite the fact that the "response header" to CONNECT <removed>:443 HTTP/1.1 is

HTTP/1.1 200 Connection Established
Misc: Proxy-Agent: IWSS

Is there any way to decrypt HTTPS traffic generated by applications other than web-browsers?
I guess that the issue may be related to some conflict with the corporate firewall Trend Micro InterScan Web Security Suite (IWSS), but I'd appreciate some ideas / advices.

Thanks,
Salvatore

How to modify the response automatically?

Hi

First of all let me make it more clear. "Fiddler is the one and only, by far the best." (Though I wish it was available on macOS too!)

TBH I'm so new to web debugging. Just having a problem using Fiddler. So let me try to be brief and clear.

I'm visiting a website almost everyday. After logging in, the browser try to send a dynamic long GET request including lots of random characters in its URL.

Nothing to do with the request because the response is the key. Actually, the responds contains a text and I'm going to just eliminate few characters before the response being received by the browser. That's all!

As you can see, it can be done manually but it's so time consuming to do each and every time every hour.

To do that auto, I'm dealing with 2 main problem. First, having no idea how to detect those long random GET requests to Fiddler to make a breakpoint after them and also no idea how to tell Fiddler to try to eliminate the last 10 characters of their response.

I did my best to be clear. Let me know please if it's not. I really need some kind of help.

Thank you.

Is it possible to capture https traffic from android 7 or IOS 13?

It works fine on a android 5.1.1 once I installed the root certificate issued by fiddler.

But seems the certificate doesn't work any more with Android 7 and IOs 13.

Fiddler keeps saying the connection is not in private even I have installed the certificate when I tried access any https website(for example:https://freematch.date)

any tricks here? or it is impossible?

thanks for your time.

Translate Postman format to Fiddler

My client's developer sent me a Postman Post Request Body in a format that I'm not sure how to enter into Fiddler 4.

In the Postman Body (raw):

{
              "userCredential":
              {
                             "userId": "myemail80@mailhost.com",
                             "password": "Password1"
              }
}

I copied just the UserId and password parts into the top part of Fiddler composer, and other values in the lower "Request Body" in Telerik:

userId: myemail80@mailhost.com
password: Password1

Do I need to encode "userCredential" and if so, how?

I am a bit confused between terminologies Request Body and Request Header between Postman and Telerik.

Testing using Postman I get a OK 200 return. In Fiddler I am getting
"statusCode":1,"errorType":3,"errorCode":9200,"errorMessage":"Missing mandatory data in header"}}

Thanks,

Fiddler change API server response?

Hello, I am trying to use FiddlerScript to change a json response from my API server to my client. I keep on getting an error when I have my client connect to the server. I am new to FiddlerScript so I don't know if I am doing anything wrong.

This is the code I am using in Fiddler ScriptEditor:

01.// Here is code to modify server's response

02.if(oSession.host == ("api.server") && oSession.uriContains("/config/url/1")) {

03. // Color this response, so we can spot it in Fiddler

04. oSession["ui-backcolor"] = "lime";

05.

06. // Convert the request body into a string

07. var oBody = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);

08.

09. // Convert the text into a JSON object

10. var j1 = Fiddler.WebFormats.JSON.JsonDecode(oBody);

11.

12. //Change the value

13. j1.JSONObject["data1"]["data2"]["data3"]["data4"]["Value"] = "1000";

14. j1.JSONObject["data1"]["data2"]["data3"]["Value"] = "1000";

15.

16. // Convert back to a byte array

17. var modBytes1 = Fiddler.WebFormats.JSON.JsonEncode(j1.JSONObject);

18.

19. // Convert json to bytes, storing the bytes in request body

20. var mod = System.Text.Encoding.UTF8.GetBytes(modBytes1);

21. oSession.RequestBody = mod;

22.}

23.

24.// Here is code to modify server's response

25.if(oSession.host == ("api.server") && oSession.uriContains("/config/url/2")) {

26. // Color this response, so we can spot it in Fiddler

27. oSession["ui-backcolor"] = "lime";

28.

29. // Convert the request body into a string

30. var oBody = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);

31.

32. // Convert the text into a JSON object

33. var j2 = Fiddler.WebFormats.JSON.JsonDecode(oBody);

34.

35. //Change the value

36. j2.JSONObject["data1"]["data2"]["data3"]["data4"]["Value"] = "1000";

37. j2.JSONObject["data1"]["data2"]["data3"]["Value"] = "1000";

38.

39. // Convert back to a byte array

40. var modBytes2 = Fiddler.WebFormats.JSON.JsonEncode(j2.JSONObject);

41.

42. // Convert json to bytes, storing the bytes in request body

43. var mod = System.Text.Encoding.UTF8.GetBytes(modBytes2);

44. oSession.RequestBody = mod;

45.}

46.

47.// Here is code to modify server's response

48.if(oSession.host == ("api.server") && oSession.uriContains("/config/database")) {

49. // Color this response, so we can spot it in Fiddler

50. oSession["ui-backcolor"] = "lime";

51. FiddlerApplication.Log.LogFormat(oBody);

52.

53. // Convert the request body into a string

54. var oBody = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);

55.

56. // Convert the text into a JSON object

57. var j3 = Fiddler.WebFormats.JSON.JsonDecode(oBody);

58.

59. //Change the value

60. j3.JSONObject["Value"] = "1";

61. j3.JSONObject["data1"]["Value"] = "1000";

62.

63. // Convert back to a byte array

64. var modBytes3 = Fiddler.WebFormats.JSON.JsonEncode(j3.JSONObject);

65.

66. // Convert json to bytes, storing the bytes in request body

67. var mod = System.Text.Encoding.UTF8.GetBytes(modBytes3);

68. oSession.RequestBody = mod;

69.}

70.

71.// Here is code to modify server's response

72.if(oSession.host == ("api.server") && oSession.uriContains("/config")) {

73. // Color this response, so we can spot it in Fiddler

78.

79. // Convert the text into a JSON object

80. var j4 = Fiddler.WebFormats.JSON.JsonDecode(oBody);

81.

82. //Change the value

83. j4.JSONObject["Value"] = "1";

84. j4.JSONObject["data1"]["Value"] = "1000";

85.

86. // Convert back to a byte array

87. var modBytes4 = Fiddler.WebFormats.JSON.JsonEncode(j4.JSONObject);

88.

89. // Convert json to bytes, storing the bytes in request body

90. var mod = System.Text.Encoding.UTF8.GetBytes(modBytes4);

91. oSession.RequestBody = mod;

92.}

I have attached screenshots of the setup and the error codes.

Can Fiddler be used to throttle an Android's or iPhone's network connections

I test mobile applications on both Android and iOS. I've tried using Fiddler running on a desktop PC to monitor an Android phone's network connections.

Can Fiddler running on a desktop PC be used not only to monitor an Android's or iPhone's network connections, but to throttle (slow down the speed, in a controlled manner) the mobile device's network connections? If so, how?

Thank you.

Fiddler keeping sockets open when in proxy mode

Hi,

I'm using Fiddler4 to capture from an iOS 13.3.1 device, with the iOS device set to Manual Proxy mode and necessary certificates installed on both end. Overall, works very well.

But there is a problem. For every socket opened by the iOS that goes via the proxy is never closed again. So the connection from iOS to Fiddler4 appears to be closed ok. However the socket from Fiddler4 to destination device stays open until I shutdown Fiddler.

The result of this is that on connection limited devices, they run out of available connections and it all stops working.

I've wiresharked the session when not going via Fiddler and iOS is correctly closing the socket (FIN state is sent).

When I wireshark the Fiddler4 proxied session the socket just stays open based on the socket is open from between my PC running Fiddler and the destination device.

Is this a known problem? If yes, is there a work around?

Best regards

Steve
