Hi Eric,

I know that Fiddlercore can only intercept http/s traffic.

Can you recommend or do you know of any c# api's that can intercept/capture these types of traffic (Similar to how fiddlercore does it):

RTSP 
MMS 
MMST 
MMSU  

Basically I just need to capture there bytes response and any other associated data.

Thanks

I have a teacher that wants to see activity on their ipads live while in class to bust kids not doing what they are supposed to.  Is there a remote viewer?  Or do I have to let the teacher remote into the server? (scary)

Thanks

Our firewalls are indicating that the host fiddler2.com (50.56.19.116) is sending traffic from its port 80 to our client which is being identified as potentially malicious malware. I am quite sure that this is a false-positive, but can anybody list the possible ways in which a client and a telerik server will communicate?

Hello Everyone, 

I am a first time Fiddler user and I could use some help.
I have an ipad app hard coded to go to https://server1.com and i need it to go to http://server2.com

So I added...

if (oSession.HostnameIs("server1.com")) {
oSession.hostname="server2.com";
}

the app is hard coded to use https port 443 with server1, and server2 has https working with a self signed certificate  I think it is failing because of cert mismatch, i see it is tunneling to server2:443 in the capture, but still getting connection refused.

What is the easiest way to get this working?

Thanks in advance for any help you can provide.

Hello, the only way I can get HTTPS to work is when I have my browser setting to include our company's enterprise (forward) proxy, so that when Fiddler starts, that enterprise proxy is next in line. If I instead have the browser set as "No ​proxy" before starting Fiddler, then an HTTPS connection will fail with a 502 once Fiddler is started.

Using WireShark to do a network trace, I can see why things are failing:

1) Once Fiddler is started, the browser has a proxy (Fiddler), and so it starts a CONNECT handshake when doing HTTPS.

2) Fiddler *forwards* the CONNECT to the web server, as if the web server were instead itself a proxy. Because the web server is not listening on port 80 (which CONNECT uses), this fails with a 502.

It seems like when there was no proxy before Fiddler started, it should "swallow" all CONNECTs and not forward them to the target web servers.

What am I missing here?

Thanks, Steve

Hi,
I am customising my fiddler script and was hoping to get the response body as a base64 string, is this possible?
I tried the following:
var bytes = Encoding.UTF8.GetBytes(oSession.GetResponseBodyAsString());
var base64 = Convert.ToBase64String(bytes);
FiddlerObject.log(base64);
However this did not work. I am probably missing something really obvious.
The response body is a PNG.
Many thanks
Pete
