Hello. Please how can I use script to click on button run to completion ? I need do this: after breakpoint edit response after some seconds run to completion automatic. Thanks for help.

I am developing a .Net application using FiddlerCore package. I setup a proxy where there are multiple clients(Internet Explorer) running to connect to a same server thru websocket.The proxy program is monitoring all those websocket messages, but is there any way to differetiate the websocket messages belong to which client process? Thank you.

Fiddler did not bring back my os settings when it crashed, moreover it did not restore them even after restarting the os. The problem is that fiddler itself also uses system proxy settings, so I can't run it to get my internet connection back.
How can I get my os settings back before using fiddler?

I have setup Fiddler as a Proxy on my iPhone and its working fine on nearly all apps. I can see http and https traffic. When I open websites or apps I can see the traffic and everything is working fine. BUT one specific app which if want to inspect (Mark-E) I don’t see any request while the app is working fine.

Hi, I'm using Cisco AnyConnect secure mobile client ver. 4.8.02042 on macOS Catalina 10.15.7 (19H114) to access the Kibana service for Client project. without AnyConnect we cant access Kibana.
I've to capture some network requests from the Kibana using Fiddler tools for debugging purposes. but when I start AnyConnect Secure Mobile client Fiddler doesn't work or capture any network traffic and if I stop AnyConnect both Fiddler starts capturing network requests.
I have Fiddler Everywhere Version : 1.4.1 Built : Tuesday, December 15, 2020 and i have verify the Mac Proxy Settings when AnyConnect is running and not and everything is the same as  here (https://docs.telerik.com/fiddler-everywhere/knowledge-base/troubleshoot-mac-proxy-settings#verifying-mac-proxy-settings) so i assume that the proper configuration is set.



Thanks in advance.

When I look at the HTTPS certificates generated by Fiddler these certificates have a validity period of more than 3 years. 

 

As more and more web browser do not accept certificates that have a validity of more than one year this leads to problems that valid certificates are rejected by the web browser just because the long validity. 

I already ran into this problem using Chrome for Android...

 

Is there an option to configure the default validity period of the generated certificates?

I have one specific browser instance that I have configured to always use fiddler, I turn on and off others as needed.   I'm doing development work and I want to see what's actually being sent back and forth, but, I really only care about my stuff.

I launch fiddler with my PC, and I have the "Capture traffic" turned off and the setting "Act as system proxy on startup" is not checked in the connections tab.

Other application on my system are still finding and using fiddler as it's proxy server, frequently causing failures.

How do I "hide" fiddler so that other systems like skype and google drive don't use it?   

It impacts me negatively in 3 ways. 

First, I only want to see traffic that I send to fiddler, I have to go out and delete a bunch of stuff.  I can remove them with filters and probably find a way to make my filters "stick" and survive reboot.   I'd have to research that.

Second and more importantly, I decrypt https, which fails on application that are not configured to use the self generated signatures.

Third, when I do shut down fiddler, the apps that have auto-detected it and configured themselves to use fiddler, still want to use fiddler.

I have a certain Android app that's not publicly available so you won't be able to fully troubleshoot, however I can explain the behavior I'm experiencing. 
When I attempt to use the app when  'Decrypt HTTPS Traffic' is disabled, the app works, but the data is encrypted and Fiddler prompts me to configure the settings.
When I enable 'Decrypt HTTPS Traffic' the app does not let me do anything and simply says 'network unavailable.' 
I did install the Android certificate. I tested on several other apps and don't appear to be experiencing the same problem. Any ideas on how I can further troubleshoot this?

the application url is here:

I called CertMaker.createRootCert () returns false,

But I don't know what causes this situation?

How to solve this problem?

If createrootcert() fails, calling trustRootCert() will crash the application

Hello everyone!

I'm using fiddler to try and replace one js file with another. I've uploaded the js file to dropbox and created a link to it.

In the Fiddler ScriptEditor, under OnBeforeResponse, I've added the following code:

if (oSession.url==orig_url) { // literal url in code
    oSession.url = dropbox_url; // literal url in code
}

Loading the website that loads the js file I've noticed that no changes were made. I looked at the captured traffic in fiddler and see that indeed a request is made to dropbox_url but the response received is an old version of the file (incorrect Last-Modified header included). Copying the url from the captured request and putting it in my browser does indeed download the new version, so the problem isn't with the url itself.

I tried the Clear Cache button and Disable Caching under Rules->Performance but this odd behavior persists.

Does anyone have any idea why this is happening and how can I fix it?

Slightly unrelated, does anyone have a suggestion for a better approach to what I'm trying to do?

Thanks,

Neil
