Hi,

I have HTTPS Decryption enabled and I have gone through all the steps to have my iOS device proxy through my PC INCLUDING trusting the fiddler CA cert from General>About. I know the Decryption I’d working because I can see the contents of other HTTPS requests in my session list. If it helps, I suspect that the traffic I’m attempting to inspect is an HTTP upgrade handshake for a web socket connection.

on other threads it seems like people are describing the same issue I’m having but the solutions are always: “enable HTTPS Decryption” or “regenerate your certificate” or “regenerate your private keys” but I do not think these are the solutions because I have tried all of them except the private key regeneration one and I am able to see the decrypted results of other HTTPS requests. 

thank you

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.

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.

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.
