Hi guys

 

I use Fiddler to monitor traffic on our router using my own spare laptop as a server. However I often end up with memory exceptions due to 'updates' on the host server machine. How do I amend the settings so it captures the external data I have it set up for (which works well)  but not my 'host' machine (which i don't need) or is this not possible??  . I am not 'that' teccy , so simple terms please of go to......., click........ etc would be helpful and appreciated.

I wonder if there's JMeter extension for import/export sessions to/from Fiddler?

If not, is it in the roadmap/future plan?

Currently only export to HAR file and convert HAR to JMX is available.

 

when run "mono Fiddler.exe", i am getting below error, any idea?

Browsing to the api https://api.binance.com/api/v1/time returns the appropiate JSON data while using fiddlers composer with standard settings (also tried no proxy) returns 502.

 

HTTP/1.1 502 Fiddler - Connection Failed

Is there a obvious problem with https that I am missing? Thanks in advance

Hi, 

I am trying to get the HTTP/WS Calls from the browser driver using the proxy.  I have configured chrome driver to use the proxy as shown below.

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
            // Create a new proxy object and set the proxy
            Proxy proxy = new Proxy();
           proxy.setHttpProxy("localhost:8888");
           proxy.setSslProxy("localhost:8888");
            //Add the proxy to our capabilities 
            capabilities.setCapability("proxy", proxy);
            //Start a new ChromeDriver using the capabilities object we created and added the proxy to
             driver = new ChromeDriver(capabilities);

If Fiddler is opened in my machine, it captures all the calls from the driver and i can export the calls manually. 

Is there any API for Java to interact with Fiddler so that I can start Fiddler before my execution starts and Export the Calls as HAR whenever I need and Close Fiddler once my execution gets complete. 

I found a jar Fiddler 2.3.3 in Maven repo but I don't know the usage of this jar. 

https://mvnrepository.com/artifact/org.apache.river/fiddler/2.2.3

can anyone help me on this?

Share me the java code samples to interact with Fiddler.

 

 

 

Hey, i have an iphone running ios 8, and i've set up a VPN to my home router (running DD-WRT). Is it possible to capture data from my mobile even if i'm not on my home network, but connected to it via VPN?

Hello,

is it possible to redirect traffic with fiddler from "https://one.servername" to "http://another.servername"

I tried to add next to FiddlerScript:

        if(oSession.HostnameIs("servername.com") && oSession.isHTTPS){
            oSession.hostname="another.servername.com";
        }

And it redirects but to HTTPS and not HTTP. Is there a way to set oSession to HTTP? or any other way to handle that redirection?

Thank you.

 

Hi, I have the following scenario: 

Open Chrome browser in proxy using Selenium WebDriver (Selenium 3.9.1, Latest versions of Chrome and ChromeDriver).

Navigate to the page https://www.playbuzz.com/termsofuse

Navigate to the page https://www.playbuzz.com/stephanganev10/which-old-school-dating-show-would-you-have-totally-won

When I navigate to the second page, FiddlerCore doesn't capture any HTTP traffic. If I open Fiddler application, I also don't see any HTTP traffic captured.

However, when I open this page without proxy, I can see all the HTTP traffic.

Can anyone please help me?

Thanks

 

Hello.
I am willing to modify a response with Fiddler's Auto Responder and I was wondering, is there a possibility to make changes on the website through Fiddler without actually refreshing the page? Thank you!

Hi

 

When i test our domain URLs with Fiddler I get a 502 error for the pages. Although the pages do exist. If i then test them in Screaming Frog i get the correct status code 200. Has anyone any idea why this could be happening? 

Could it be something to do with Akamai and the Bot Manager blocking Fiddler?

Thanks

Mark
