How to capture an SSL GET request with FiddleCore

Question

I'm trying to get the full HTTPS url for each request. So far I'm getting only a CONNECT request with the domain url

How can I get the full URL request?

This is my code so far

Fiddler.FiddlerApplication.BeforeRequest += FiddlerApplication_BeforeRequest;
Fiddler.FiddlerApplication.BeforeResponse += FiddlerApplication_BeforeResponse;


if (!Fiddler.CertMaker.rootCertExists())
{
   if (!Fiddler.CertMaker.createRootCert())
   {
       throw new Exception("Unable to create cert for FiddlerCore.");
   }
}

if (!Fiddler.CertMaker.rootCertIsTrusted())
{
   if (!Fiddler.CertMaker.trustRootCert())
   {
      throw new Exception("Unable to install FiddlerCore's cert.");
   }
}

Fiddler.FiddlerApplication.Startup(0,
            FiddlerCoreStartupFlags.Default |
            FiddlerCoreStartupFlags.AllowRemoteClients |
            FiddlerCoreStartupFlags.DecryptSSL |
            FiddlerCoreStartupFlags.MonitorAllConnections |
            FiddlerCoreStartupFlags.RegisterAsSystemProxy |
            FiddlerCoreStartupFlags.ChainToUpstreamGateway |
            FiddlerCoreStartupFlags.CaptureLocalhostTraffic);



void FiddlerApplication_BeforeResponse(Session oSession)
{
        if (oSession.uriContains("youtube"))
        {
            Console.WriteLine(Osession.fullUrl());
        }
}

void FiddlerApplication_BeforeRequest(Session oSession)
{
        if (oSession.uriContains("youtube"))
        {
            Console.WriteLine(Osession.fullUrl());
            oSession.bBufferResponse = true;
        }
}

With the browser help I'm trying to reach https://www.youtube.com/watch?v=v-gzrWQO7VI URL. Can the fiddler catch it?

Thanks a million. Ran

Sure, Fiddler can capture this. If you're only seeing the CONNECT that implies that the client isn't trusting Fiddler's certificate. You should put back the lines that log notifications and errors; my guess is that you'll see one noting that makecert.exe isn't where it belongs.

Your code above will not compile since OSession isn't the same as oSession.
