I want use Fiddler Script and I have those packets with this host name :

wl.search.ar.ns.test.com

If I use oSession.HostnameIs how can I do ?

So ? 

if (oSession.HostnameIs("wl.search.ar.ns.test.com")) {
            oSession.hostname="199.156.34.12";
}

is it correct ?

I don't know what "how can I do ?" means. What specifically are you trying to accomplish?

The code that you wrote, when placed inside the OnBeforeRequest method of your FiddlerScript, will change the hostname of any request for the specified hostname to the specified IP address.

The Tools > HOSTS... command in Fiddler works similarly, but also fixes up HTTPS certificates, etc.

Howdy, Marco--

I still don't understand what problem you're having? What specifically are you trying to do, and what exactly happens?

Fiddler works with any program that supports a proxy, which is essentially anything written in Java, .NET, C++, etc. Sometimes, poorly-written programs will not automatically use the system's proxy settings and must be manually configured to use the proxy (127.0.0.1:8888) but telling me what the program you're using is will help.

No, you don't need to reboot anything.

What version of Windows are you using?
Do you think the application in question is using WinHTTP? If so, is it a 32bit program or a 64bit program?

What, specifically, is the application?

Does it use HTTPS? Have you enabled HTTPS decryption in Fiddler? Have you trusted Fiddler's root certificate?

Hi, Marco--

The "Windows Phone Emulator" isn't really an application at all-- it's a virtual machine. As such, there are special requirements you need to follow in order to get its traffic captured. Have a look at http://stackoverflow.com/questions/23462697/windows-phone-8-1-emulator-not-proxying-through-fiddler and if you still have problems, please provide information about what version of VS and Windows you're using.
