Are the fiddler libraries available for us to use?  I need to write an application that logs HTTP URLs visited.  Fiddler obviously does this very well.  Can I reuse your libraries or include fiddler in my windows service to accomplish this?

http://blogs.telerik.com/fiddler/posts/13-01-08/capturing-traffic-from-.net-services-with-fiddler gives an example of how to capture traffic from .NET apps. It doesn't work for me.

I am running Sitecore 6.6, a venerable .NET app, in 64 bit mode on IIS on Windows 2008 R2 x64.

I made the recommended changes to the machine.config files in both C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config (this is a 64 bit app, so this one is probably the one in use) and C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config. I know that this has an effect because when I make a mistake to the Framework64's machine.config, I get a 503 error.

Anyway, I have a feature in Sitecore that reaches out to another server via HTTPS (SharePoint Integration Framework, aka SPIF). Fiddler does not catch this. All Fiddler catches is traffic generated by my (user mode) web browser.

If .NET application traffic was being routed through a proxy, then the Sitecore SPIF feature that reaches out to the other server would fail.

Oh, I know that Sitecore SPIF is indeed reaching out because Wireshark shows the traffic.

If Fiddler captures .NET application HTTP traffic, why is it not doing it here?

Is there an option (4.4.8), or can we get an option, to configure the extended checks for protocol violations that Fiddler performs? I'd like to leave Extended checks on to see what drops out. However we're not using absolute-uris in our redirect responses (yes, technically a violation, but we don't care) so I'd like to disable that check as the window quickly fills up with that violation. Is there some hidden config file for HTTPLint? I didn't see it.

Hi Erik,

I just checked the documentation page about on how to customize the tab icon and it seems not to be not right: See screenshot: http://screencast.com/t/TMl6KESEH

Page: http://docs.telerik.com/fiddler/extend-fiddler/addicon

Please correct me if I'm right about this script:

public void OnLoad()
{
oPage = new TabPage("Timeline");
Image newImage = Image.FromFile(@"C:\Users\.........");
FiddlerApplication.UI.imglSessionIcons.Images.Add("imgKey", newImage);
oPage.ImageIndex = FiddlerApplication.UI.imglSessionIcons.Images.IndexOfKey("imgKey");
oView = new TimelineView();
oPage.Controls.Add(oView);
oView.Dock = DockStyle.Fill;
FiddlerApplication.UI.tabsViews.TabPages.Add(oPage);
}

Thanks,

Hello Forum,
I work for a company called ePay and I was wondering if someone could assist me with a certificate issue.
Our company uses a Digital Certificate with our customers and it seems we might be having some compatibility issues with Fiddler.
My question is the following:
Since we have a certificate installed and imported into the browser (e.g. IE10) and then Fiddler adds a Do_Not_Trust_FiddlerRoot Certificate which causes the compatibility issues. I read that a fix would be to move the certificate from the personal folder to the "Trusted Certificates" folder, but I want to confirm this would be the ideal fix and that I wouldn't disrupt or disconfigure any settings in Fiddler.
And my second question is;
What type of problems could we expect if the Do_Not_Trust_FiddlerRoot is left on the personal folder? (problems with OUR certificate)
And my last question is:
Would any configuration be lost if they DELETED the Do_Not_Trust_FiddlerRoot certificate?

Thanks for the help.

Hello, I am using Fiddler and have a filter set to capture sessions. I have not used it in a few weeks and when i went on today, it is not capturing anything. I have checked all my settings Capture traffic is enabled, i went through all the options and it is not recording anything. i tried it on ie and on firefox and its not working on either.

Environment: Fiddler 4.4.6.2 64-bit on Windows 8
Proxy server in the browser was manually set to localhost:8888.

Problem: when Fiddler is told to NOT capture traffic (the icon in the left bottom corner disappears) Fiddler still captures traffic and displays it.

Basically there is no way to temporarily disable capturing other than disabling proxy in the browser. This is very inconvenient, especially in a VM environment.

Hi,

I've a issue with a computer when I launch Fiddler.
Every URL address I want to request is bloqued while capturing is enabled.

If I stop capturing, URL request are passing.

My version is up to date,

I've tried to unistall and clean it, then re-install it without success.

What is strange about it is that I don't have this issue with an other computer with the same configuration, params, and antivirus options.

I've only found one topic about it on google, and the guy solved it with an uninstall (unfortunatly it doesn't help me there :/)

For information, in help > about, it's written 'No Gateway' on both computers.

If you have any information or tips to help me to solve this matter I'ld be very grateful ;)

Hello,
we are trying to automate web browser control through powershell and we are using FiddlerCore to get the time statistics. Basically trying to get the total time taken by a website to finish loading.  

We call start-Fiddler to use it as proxy and then create a browser control.
Now we Navigate to page and then call $output = Receive-Fiddler.

Now there seems to be a problem with output returned through this command "Receive-Fiddler". It basically returns an array of requests made and the time statistics [ ClientConnected , ClientDoneResponse ]. often I see the ClientConnected , ClientDoneResponse is coming as Null. Again this is intermittent but can happen atleast  5-6 times in 10 tries. its easily reproducible.
 ($result[0].Timers.ClientConnected )


has someone reported this behavior? is there an better approach than what we are doing?

thanks for your help

I have connected an iPhone to my Win 8 machine and configured Fiddler to with instructions found here http://blog.brianbeach.com/2013/01/using-fiddler-with-iphoneipad.html

So far all seems ok in that when I access a website on the iPhone its logging it and I can see where its going etc. I then need to monitor https requests by that I mean a site in the format of someSite:443.

When I access an app using this mechanism the application freezes and returns an error (cant connect) which I assume is to do with the traffic going through port 8888 - what additional steps do I need to take in order to capture the URLs that the app is hitting?
