Hi - When I try to create, or import an encrypted save file, or try to open an encrypted save file, I receive an error: "Value of 'null' is not valid for 'stream'.".  It does not appear to break the process, it still asks for a password, it still seems to save the file, and it still seems to import the file.   I am running version v4.6.3.50306.

Here is the information garnered from the CTRL+C:

Here is my layout to start.

 

I am trying to get www.mysite.com/blog/ to rewrite to blog.mysite.com.

Both of them are separate IIS Websites on the same server.

 

I discovered that the way to do it was ARR.

 

I have set it all up and it works, but here is the problem.

It only works when I set the Proxy Chain to localhost:8888 and fiddler is running.

But otherwise, it does not work.

I don't want to leave Fiddler running all the time.

 

What can I do?

Hello,

I'm trying to capture remote traffic of an iOS App but unlike other Apps this one gives a problem.

When i use the app with "Decrypt HTTPS Traffic" enabled, the app simply says "Network Unavailable". I tried using both the root certs (MakeCert and CertEnroll) but still i have the issue.

But i have tried various other apps and they never had an issue like this.

Protocols - <client>;ssl3;tls1.0

Hi everyone. Basically the issue im having is that I want to capture and decrypt traffic from a program. The issue is that nothing related to it shows up on Fiddler.

Yes I already checked the filters, everything is fine and also tried removing and reinstalling the certificates. The odd part is that Net-peeker 3.50 can capture the packets but of course I can't decrypt the traffic.

Any suggestion will be greatly appreciated.

Thanks.

 i use fiddler autoresponder to ensure that tools do not break out to other domains. 

attached you can see how i configured it in the past.

today after month of upgrade questions and 100 "NO!" i updated and now exactly this features is buggy. 

the regex tester shows that the regex is  valid but the requests gets *reset.

for example this rules allows only amazon pages regex:(?inx)^(?!http.\:\/\/[a-zA-Z0-9\-\.]*amazon\.com).*$

check the attachment. with version v4.6.2.32002 its working

with v4.6.3.44034 not

thx

Okey guys im new in feddler. Now i am participating in a internet poll. This poll can give 1 vote in 3 hours. Can i give multiple votes in same time?

I have been using Fiddler successfully for several years, intercepting the web traffic from Hi5, to enable my own software to automatically play its game . Hi5 have this week changed something, somehow hiding some of the traffic so that my software now does not work. Has anyone any idea what they have done? or ideas for seeing the missing traffic?

Hi, 
I want to run a selenium test on my local machine and catch http traffic on different machine.
This is my script:

RemoteWebDriver driver;
ChromeOptions chromeOptions = new ChromeOptions();
FiddlerApplication.Startup(8888, FiddlerCoreStartupFlags.Default);
OpenQA.Selenium.Proxy proxy = new OpenQA.Selenium.Proxy();
proxy.HttpProxy = "{IP of the different machine}:8888";
chromeOptions.Proxy = proxy;
DesiredCapabilities capabilities = (DesiredCapabilities)chromeOptions.ToCapabilities();
driver = new RemoteWebDriver(new Uri({IP of the different machine}:4444/wd/hub), capabilities, TimeSpan.FromSeconds(600));
FiddlerApplication.AfterSessionComplete += CollectDataThroughProxy;



private static List<string> dataStr = new List<string>();


private static void CollectDataThroughProxy(Session sess)
        {
            if (sess == null || sess.oRequest == null || sess.oRequest.headers == null)
                return;
            string headers = sess.oRequest.headers.ToString();
            var reqBody = sess.GetRequestBodyAsString();
            dataStr.Add(reqBody);
        }

When I change IP in the code and run it on my local machine, it works fine. However, when I change IP to different machine, I see the relevant page is open,but I don't get the http traffic from this machine.
I checked "allow remote computers to connect" in Fiddler options.

Can anyone please help me?
Thanks
