I want to monitor the Apex DataLoader SOAP requests via Fiddler and as a first step I have imported the Fiddler Certificate in to "cacerts" in jre/security location in both DataLoader installation and JDK installation paths. Now I am able to perform import and export operations from Dataloader via Fiddler, but I see only Connect (Grayed out Tunnel) traffic. How to see the complete SOAP request and response?
Solved :-). Exported the Fiddler cert from Personal Certificate Store (see-here) then placed it at %USERPROFILE%\Documents\Fiddler2 location and restarted Fiddler. I can now see the full soap requests and responses. BTW the OS is Windows7, DataLoader version is 25.0.0 and Fiddler-2.4.10.

I want to capture traffic from a host using HTTP, but I do not see a response coming back. If I close fiddler, my application runs as normal.
I see '-' in the Result section, where it should have been an HTTP response code. If I manually execute the request using Composer, I get a 200 response. Fiddler is able to capture traffic from all other web applications without issue.
I have installed Fiddler certificate. Troubleshooting Mode returns 200. The host does not use HTTPS, but I have enabled Capture HTTPS Connects anyways.
I am using Fiddler v5.0.20182
Some applications performs certificate pinning. Also web applications can perform certificate pinning e.g. via HTTP Public Key Pinning (HPKP). If you have ever used the web application in your browser without Fiddler, the web app public key has been downloaded and cached in the web-browser.
Afterwards the Fiddler root certificate is no longer accepted for that site/app even it it has been installed correctly. You should be able to identify such problematic connections in Fiddler if you only see a CONNECT request but no subsequent requests to the same domain.
To delete the HPKP in your web browser you should use a fresh profile or clear the complete browser cache. Afterwards only use it with activated Fiddler proxy and SSL decryption. As far as I know Fiddler will remove HPKP data from responses so that the web application should also work with Fiddler in between.
I think you should be able to uncheck the options for https, uncheck the boxes which appear checked here? Or you might be able to skip decryption by adding the host in the box below where it says Skip decryption for the following hosts
I am using Apex (Force.com) to send HTTP requests to a server that is hosted on AWS. How can I know if the server I am sending the HTTP request is using a valid certificate and my request will be encrypted before being sent out? I know I'd be able to look for the lock icon on the browser but since this is a RESTful API callout, I'm not sure how to do that. I found one similar question here and the answer seems to be PHP specific.
Message Analyzer Tool would help you here and this tool will track all communication including encryption.
Please install Message Analyzer tool in your client OR server environment and track the message.

I am trying to send out a WebRequest request like https://identityserver.github.io/Documentation/docsv2/advanced/clientCerts.html specifies with a handler containing the Client Certificate.
I've gotten to the point that i have determined that the ClientCertificate is just not being sent through fiddler, so it is not read in the ServerVariables["CERT_FLAGS"] when the Owin LoadCertificate is called.
So i have removed all the steps from the process except (IdentityServer3.Samples/source/Clients/ClientCertificateConsoleClient/Program.cs)
async Task<TokenResponse> RequestTokenAsync()
{
var cert = new X509Certificate2("Client.pfx");
var handler = new WebRequestHandler();
handler.ClientCertificates.Add(cert);
var client = new TokenClient(
Constants.TokenEndpoint,
"certclient",
handler);
return await client.RequestClientCredentialsAsync("read write");
}
but I am still not seeing in fiddler in the raw request the certificate. I have looked at the source code for HttpWebRequest and only see it handles the ClientCertificate in the GetConnectionGroupLine, and then its a hash code which i also don't see in fiddler. I'm working with Windows 7 and i have turned on the iis client certificate mapping authentication and enabled the setting in iis express applicationhost in the 2015 .vs subfolder and the primary one in my docuemnts. What am I missing here?

TLDR: Your problem (at this point) is Fiddler not HttpWebRequest/dotnet. (Edited to clarify.)
Fiddler doesn't display TLS info including certs. Fiddler works on, and displays in numerous formats, the HTTP-level data (requests and responses, including application data). When HTTPS transports this HTTP data over SSL/TLS, Fiddler does not display the SSL/TLS-specific data, which in addition to server and optional client certificates (currently) includes version, suite, possibly compression, curve, format and next-protocol negotiation, nonces, ephemeral keys, renegotiation control, signature algorithm control, server name indication, ticket, and other crypto options like encrypt-then-mac and extended-master-secret. The "raw" tab displays all the HTTP data without interpretation, but not the SSL/TLS data.
Fiddler doesn't request client auth. An SSL/TLS session uses a client certificate to perform client authentication only when requested by the server, and when your client connects to the real IdentityServer it presumably requests this. But when Fiddler is used, there is one SSL/TLS session from the client to Fiddler, and an entirely separate SSL/TLS session from Fiddler to the server. On the session from your client to Fiddler, Fiddler does not request client authentication, so your client doesn't and can't send or use its certificate.
Client auth can't be relayed anyway. If Fiddler did request client auth on the session from your client, it couldn't use that information to authenticate the session to the real server. Client auth doesn't just send the client cert, it also uses the private key to sign the concatenation (called a transcript) of the handshake messages. Since the handshake between your client and Fiddler and between Fiddler and the server are quite different, this signature is invalid for the server-side handshake and sending it would (correctly) be rejected as invalid by the server.
Instead Fiddler can do the client auth. If you want to route HTTPS traffic using client auth through Fiddler, you need to instead configure Fiddler to do the client auth on the session with the server; for a fixed setting you can just drop the identifying certificate in Fiddler's config directory, for per-session settings you need to write some FiddlerScript. The private key (and chain) needs to be in the Windows cert store, not (just) in a file. See:
http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/RespondWithClientCert
https://www.fiddlerbook.com/fiddler/help/httpsclientcerts.asp

If your actual problem is getting the client to support client auth when NOT using Fiddler, you need to take Fiddler out of the situation and use other debugging tools like a network trace.
I have a web server that handles configuration set-up for various IO devices. I need to get some data from a REST server that is running on a different server. Can that web server code issue a client REST GET command to a REST server running on a different server? I tried it but I get a http 500 error. The server code is failing on the REST server request code.
I am closing out this question. Yes, your server can issue http requests to other services. I was having another problem with a self-signed certificate and the error made it look like their was a problem with my http request service.
I am creating a screen scrapping application which uses web whataspp. I want to know how the messages are being posted. I installed fiddler and enabled https and tweaked the certificates settings in it. I am unable to get any traffic from web.whatsapp.com, but fiddler is able to capture requests and responses of other websites(http, https). Please help.
